Anatomy of Game Development
CowboyRobot writes "ACM Queue has an article titled Game Development: Harder Than You Think that looks at the complexities of creating a modern game, in comparison with the relative simplicity of doing so ten years ago.
My understanding of the industry is that they have too many designers and not enough programmers. From the article: 'Now the primary technical challenge is simply getting the code to work to produce an end result that bears some semblance to the desired functionality... There's such a wide variety of algorithms to know about, so much experience required to implement them in a useful way, and so much work overall that just needs to be done, that we have a perpetual shortage of qualified people in the industry.'"

No it's not. Children make up games to play with their friends all the time. Why is it difficult to make a system? Codifying it formally is where everyone runs into problems. Oh and that everyone loves to reinvent that wheel.
As a programmer and game developer myself I have experienced first hand the level of complexity that game design and development has approached in recent times.
It used to be, and back in the day when I started programming my first games, that a single "Lone Wolf" programmer (Like I have always been) could develop his own game.
However, now with the crazily complex 3D games, there has to be a whole army of developers, artists, designers, programmers, etc. just to create a game.
Unfortunately that damages lone wolf developers such as myself, in that we cant keep up with the demands of such a large production budget!
Anyway, I have attempted to work as good as I can, see what you think of my game, it is a bit difficult to wear the hats of Programmer, Designer, Developer, Musician, and Artist!

Or is the author of this article really called Joe Blow?
Nice pen name
The hard part is not the engineering. The hard part is the game design, story line, and content creation.
So in a sense, the author is correct: game development is hard; but its about 10 times harder than he is making it out to be because he is focussing on the 'easy' bits.
Yeah, games were easy to make ten years aog, i coded a few but it was a "code" challenge, now it's different, most of the time someone built a nice engine and everyone make content for it, that's why many studios just focus on design, don't get me wrong, design it's important but programmers don't qualify often for game industry unless you want to built something new, something that is not a goal for many companies.
But hey! What do i know? I live in Mexico, there is a small or not-existant game industry at all!

It's also that there's a huge gulf between "having an idea for a game" and "being a game designer". Frankly, any idiot off the street can come up with a halfway decent idea for a game (it might not be terribly original, but it could probably turn into a reasonable game). The talent in game design lies in the thousand little decisions you have to make in turning the raw idea into an actual game. It's those little details that matter, and that separate a great game from an average game, and an average game from a bad game.
One thing I've noticed with a lot of open source game-directed projects is that they feed off each other as needed.
You can take jim's physics library and link it into fred's ROAM engine, slap tommy's interface toolkit on top if it then shoehorn bob's network protocol in and actually get a usable piece of software out of it. The SDL libraries are one obvious example of this but it's far from the only place I've seen it.
No it won't be the next jaw dropping engine that will command everyone's respect but that's not really the point, the point is as long as you have enough basic intelligence to learn an API and can manage to glue several of them together the open source world is plenty willing to fill in the gaps of your knowledge.
It isn't really an open source specific thing, this mode of thinking can be found under windows as well, but for obvious reasons it seems to flourish best in the linux world. It's not mature area of development yet, but the foundations are there. As the barrier of entry into developing commercial games increases, so to do the free software options.
I think it'll be neat to wait and see if open source can evolve to present a solution to the "kitchen sink" problems that current game development has to deal with.
Flash is a bad word for some folks here, but it really excels as a platform for simple, addictive, and fun games that can be easily spread to the world.
Working in a restricted environment like Flash eliminates a lot of the hassles described in the article. It's arguably easier to write, say, King's Quest now than it would have been 20 years ago,
Nice article, but I think it misses a key point. Game creation is only more complex these days if you're trying to build/copy a complex title.
Of course a Lone Wolf isn't going to be able to knock out myHaloTribes2! But s/he sure as heck can still tackle a simpler game, with even less effort than "days of yore" in my opinion. OpenGL, a slew of commercial games engines, cross-platform solutions, even SDKs for mobile phones.
The opportunities abound, even if the market is drowning in noise these days. The bottom line is don't try to compete with a big studio if you're not a big studio! Skip the $150K intro/cut-scene movies, etc. Don't aim for a MMORPG. Just build something fun, dammit!
Think of it as the development equivalent of asymetrical warfare.
what needs to happen, is we need a complete game enviroment to creat games, not just a game engine, but a complete piece of software that doesn't need any programming at all. think of using maya to do all your 3d models and animations and worlds for the game, and instead of exporting these out to an engine you keep it all under one roof, give the models properties like colision, key bindings to play this animation when this key is pressed in this direction etc. Of course programming should be en extensible part of it to add funtionality that might not be in it. so essentially a 3d applicaiton with a game engine at it's heart containing everything you would need to make a game. This could be done right now with directX9. The single man band could be back if this happened.
...have any of you seen the demo video of the upcoming Half-life 2 (or even *gasp* downloaded a leaked beta), I was watching in amazement wondering how games had come so far in such a little time.
Let me elaborate, splinter cell was an amazing game but the storyline was very linear and interacting with the environment pretty much restricted to shooting out lights.
Halflife 2 on the other hand allows you to use some magnetic levitating weapon that can tear metal objects like radiators from the wall and hurl them at the opposition. Boxes and furniture pushed against doors to stop attacking enemies.
I can't even begin to imagine the complexity that has not only gone into the code design but also the level design. That's the crux of it, without amazing and clever levels that leverage all of this new complexity a game falls flat on its face.

Many games take half an hour or longer to compile when starting from scratch, or when a major C++ header file is changed.
Come on, Design Patterns is only $50. Surely they can afford a copy or two? Shouldn't the public interfaces to external classes for a module be fixed pretty early on, if not at design time?
and the most popular game on the PC is still solitaire!
:-P
Here in florida we have a college, Full Sail, it specializez in entertainment industry stuff. Such as: game design and devolpment. It's good to know we have a place that specializes in making the people that are required if world of gaming is to be continued.
Lua is the embedded interpreted language of choice for game designers. Lua's great for writing the game AI (you don't have to wait for a half hour C++ build). Lua's under 200K, threadsafe, has good OO abstractions, integrates with C very easily, and most important of all - it has a commercial friendly license.
I remember when I was 13 writing ASM code code aspiring to write something like Monkey Island -- that was a very attainable goal. I had a friend who was a very good artist, he would whip up a some cells in autodesk animator, I had written a little converter, and we could walk our little guy around the screen against a background. Now truth be told I had NO idea how a game engine worked at 13 years old, but we did end up writing a few neat demos and bbs loaders (I was a weird kid).
Now the level of art work and technical knowledge required to make something that looks half professional is off the scale. I have a great game idea that I don't think I'll ever be able to realize. Thats the loss I mourn... kids wont ever have the fun I had trying to make a game, and we might never be exposed to some new ideas these kids might have.
Religion is a gateway psychosis. -- Dave Foley
There's still a market for the simpler games. Cell phone games are big. The Game Boy Advance is big and anyone can code for it. Distribution is another matter but there's nothing stopping developers from creating a product to get their feet wet. Worst case you make it a pay per download or give it away free as an ad for your PC games.
2D used to be the best choice simply because you could do infinitly better looking graphics. 3D is now getting up to par but there's really no reason not to still use 2D. The latest Wario game just took a tile based game and made it a cube based game in 3D. Not a programming challenge at all. Instead of DrawTile you just use DrawCube, increase the dimensions of your map and voila! 3D platformer. I whipped up the basic components in all of a few days (running, jumping, standing on and above things, collision).
The market is so saturated with 3D first person shooter crap that there's a huge market for games that are simply fun to play. You are not going to get rich from a 3D game so why bother making a crappy 3D game in a lame attempt to milk the 3D scene? Make the best of what you can do, even in 2D and it may not make you rich but at least it won't be half-assed crap.
Stop worrying about the million dollar budgets and just worry about making a fun product.
The best application of 2D is in puzzle games which are ginormous. The hardest part is comming up with the new puzzle concept. Programming them is rediculously easy and they're cheap. Which makes it more likely people will buy them as time killers at work to replace solitaire and minesweeper.

I worked in the games biz for 3 years in QA and production, and finally with a hiring team for engineers in our company. Let me tell you, coders in the games industry are payed jack, and work like mad. Most times, the average work week is anywhere from 80-95 hours for the coding team. I personally got out of the industry because of this. I don't think there are a lack of talented people to do it, just there are not enough people willing to put 80 hours a week in to a game for circa 40-50k, w/no OT.
First of all, any change whatsoever in header files trigger rebuilds, not just public interfaces. Secondly, core headers in theory would perhaps be fixed early on, but in practice that's just plain impossible. I can spend a lot of time here trying to explain how that comes about, but it's not worth the effort unless this message got a decent score. Suffice it to say that it's simply impossible to see into the future and know exactly how any header file really needs to be when it's finished.
I'm tired of this, I really am. When will guys like this admit that everyone else works for a living too? No, games are not always very simple. Thanks buddy, we know.
All this "Life is so hard! My industry is so cruel!" is just attention grabbing to get readers to an otherwise rather dry review article on the elements of commercial game production.
In other news, games are unimportant. All but a very few games are played by practically no one, and those that do play it throw it away after a couple-dozen hours. Where did this conception that making games was so exciting and dramatic come from? Just because so many other areas of software development are even more mind-numbing doesn't make gamedev automatically interesting!
Design me a new spoon. Design me a spoon that will be sold across the world, used by millions on a daily basis for years of their life. Design me a brilliant spoon, and I will be impressed.
is this article written by the half-life2 people to attempt to justify another 6 month wait? i wanna play it now damnit!
Sorry, Carmack is full of BS. Story makes or breaks a game in more than a few cases. Take Halo. Without the excellent story and plot devices, Halo would have been nothing but another faceless FPS. A pretty one, but hardly the best seller it was for the XBox. Story drove that game. Story seperates Baldurs Gate 2, a masterpiece, from the gorgeous but hollow Neverwinter Nights. NWN has BG2 dead to rights on every point except one, and it's that point alone that elevates BG2 to legendary status.
Of course Carmack says story is not really that important... Look at the games he designs-- FPS almost exclusively without story. It's a pretty narrow vision to be making such sweeping judgements from and it hardly makes his word gospel.

Here is an interactive game in one line of basic code (ok 4 statements, but you could write it in one basic numbered statement). Just showing what could be done with minimal code.
You control an object at the top of the screen it will move left if you don't push shift, right if you do. Blocks "###" are printed at the bottom of the screen and scroll up. If you crash into a block it is game over. Quite complex for 1 line. I would walk into stores displaying computers without games that attracted the kids, type this in and have fun.
I had versions for PET, VIC20, C64, APPLE II, TRS80 machines
Adjust for my bad memory and learning of many other languages since then.
0 poke 32788+a,65; a = a + peek(515)*2-1; print tab(36*rnd()),"###"; if (peek(32788+a) == 32) goto 0;
clear the screen, scroll to the bottom and run
Break down
A) poke - puts player "A" set by ascii 65 at the middle of the top line of the screen plus the offset a
B) adjust the offset a of the players position dependent on the state of the shift key
C) print - puts a block in a random position on the next line. If this is the bottom of the screen, we get a scroll and everything moves up and the players object is cleared off the top
D) check the new position of the player to see if it is clear
Majic numbers
32788 address of the middle of the top line of the screen
65 character for players object
36 + width of block is 1 less than the width of the screen, in this case 36+3 40
515 shift key status updated by system interrupt
Even if you make the game in such a manner as not to be "professional", you may still have a winner of a game. Stuff written in Flash is very easy to do yet brings out remarkable results.
Not every game has to be a 3d FPS or whatever. Uplink was written by a couple of guys in the UK and is one hell of a good game.
If you want to do more than a Flash game, that's quite doable as well. Writing a high end 3d engine is indeed hard stuff, but that's why we have mods! Not only can you learn a lot from the open sourced engines out there, you can use some of them to make a mod that is high quality stuff.
You mentioned artwork: well, fear not- the stuff you can do with the right tools is shocking. You can grab a copy of Blender, and after a few weeks of beating it up you will be turning out 3d models that are better than what you figured you could have made at the beginning. The GIMP is perfectly good for texturing models, and has just about all you'll need for the task (while the GIMP isn't professional photo editing software, it's great for making textures and web graphics.)
What we call folk wisdom is often no more than a kind of expedient stupidity.-Edward Abbey
Let look at a few examples:
Games have ballooned in complexity-
I think it is safe to say that nearly all software has grown in complexity. For traditional client-centric applications, we have seen interfaces grow more complicated and sophisticated. Unlike software designed in 1996 nearly all applications are now internet aware. Even your wordprocessor has the ability to communicate via the internet, to interact with email and offer colaboration functionality.
Very little software is designed to operate in the vacuum of a stand-alone workstation anymore. Apparently this is also true of games. Wow, brilliant insight.
Tools-
The author is probably correct about a lack of competing products for Windows C++ development. Still Visual C++ is quite a good IDE. A lot of the issues raised are more generic complaints about C++ development than anything specific to game development. While game programming has its own special requirements- 3D rendering for example- other types of software has different but equally complicated needs. For example, the complexities of interating with a wide variety of back-end databases, message-queueing software and legacy mainframe systems add layer up layer of complexity to most business applications. The specific requirement is game-development specific but the problem is one which all complex projects face.
Let face it, the need for source control systems which are able to manage arbitary content is hardly unique to game development. Nearly every project I have ever seen runs into source control issues.
Workflow issues
Now the issue of re-compilation times, debug build load times and other development issues are a problem for ALL big software development projects. Multi-platform issues are equally problematic. This is hardly restricted to game development
Third party components-
Always an interesting issue for application development and not exactly one confined to game development. Think about applications you have seen which manipulate data and display charts and graphs. How many of those apps actually have custom written charting libraries. Hardly any. Nearly ever application OEMs someone's ibrary with all the associated headaches that come with emebedding components over which you have no control. That is the trade-off you make. You save 10 man-years of effort in developing a graphing library and you lose control of the source code, bug-fixing, release cycles and the ability to add new, special or project specific functionality. (Unless of course you go OSS). Big deal. Highly Domain Specific Requirements-
This is the dumbest section in the article. All software has some domain specific requirement otherwise it wouldn't be an application, it would be some sort of generic framework. Games clearly have a set of requirements not found in typical application software- 3D graphics, AI and sound effects for example. However if we look at network security applications for example, I think that we can safely say that there are just as many complex, domain specific requirements involved in TCP/IP protocols, packet sniffing, network tracing , etc.
Profiling-
Profiling all code is hard. Identifying bottlenecks in code which involves a great deal of user interaction is very complicated. Hardly specific to game programming.
Reality check time. All the article says is in 2004 that users expect a far more sophisticated product than have been required in 1996. Engineering complex products is difficult. Welcome to the software industry.
I completely agree, there is also a hell of a lot of difference between having a great game 'idea' and having a great game 'idea' that is practical and fun.
There are countless examples of games that are great in theory, but poor in practice(I'm looking at you Black & White). Yet relatively few that have no business in being so great(And here I'm looking directly at a certain Tetris), and somehow pull of all those intangibles such as playability.
Even taking a great idea that 'will' be purely playable and making it so, is a great skill that only few can accomplish.
It amazes me how certain designers can almost routinely pull off the impossible.
Although I'm a programmer, I've spent time learning GIMP, blender, Sodopi (and a load of applications from other skill domains) - when no one is regulating your use of software, you're free to teach yourself what ever you want.
...free software is the way the world *should* work
It's not a qualification, but you can easily learn enough to bluff through an interview. (so long as you can tell that the job is really just a programming job with too many requirements written in the spec to make a manager feel like she's doing her job.)

For what it's worth, Yes, I am a professional Game Programmer.
From a programming standpoint, 20 hours of high quality game play is just as difficult as 60 hours. The bulk of the work for an additional 40 hours is done by artists and level designers creating the additional content.
And a shorter game does not aid its 'beat-ability'. It just aids its re-playability. Most 60 hour games can be beaten in 20 hours or less, typically, you just skip the side quests.
And doing a 20 hour game, but making more of them reeks of what EA does with expansion packs. Its a very shallow marketing ploy.
I would rather play one long well made game, then 1 short well made game and 4 short crappy games tossed off with the aim of turning out a profit.
END COMMUNICATION
The game development community used to take algorithms from other fields. Now they've gone beyond academia in graphics, physics simulation, and AI. Games are a tough, competitive market, and the stuff has to work, or you get trashed in reviews. That makes for real progress.
It's the usual story. Companies demand experience on all posts, and then whine about lack of "qualified" applicants. While ignoring the fact that they themselves are creating a qualification that's impossible to get.
Reminds me of the ads I used to see when Unix was first catching on. Entry-level pay jobs requiring 5 or 10 years of Unix experience, obviously written by HR people with no clue.

Bantam Dominique roosters crow a four-note song. Once you've heard it as "Happy BIRTHday" you can't NOT hear it that way
Every year or so I buy a game that consists of 90% 3D fluff. I just spent an hour at Dave and Busters and really enjoyed the "old" 2D interfaces because they nether helped nor hindered good games. By good game I mean something designed with regards to gameplay and not another over-done FPS maze game or cookie-cutter strategy game.
The game industry looks like the equivalant of the comic book industry in the eary 90s, lots of eye-candy, gimmick covers, etc and little substance. Seems its a technological arms race to build games that run on the newest hardware and that gameplay is the last thing on the 'to do' list.
The game I am working on right now is a week before Beta. I work for a medium sized publisher of console games. Take that as warning of my bias.
I would add several reasons to why game development is hard. All the technical issues Mr. Blow mentions, can be fixed given enough time. But there is never enough time.
To keep funding $10M+ game projects, a corporation needs to release a steady stream of games during major buying periods. This means, unless you're the likes of id or Valve, development cycles are 18 months, rarely negotiable. If you are late you will start loosing consumer awarness and marketing budgets. You also need to schedule time to do several demo disks and generate assets for the media. A senior programmer said that our primary target is management, and only later the gamer.
Second, unlike many software markets, you constantly feel your competition at your heels. The graphics, realism, complexity is an arms race. This makes games better and it also makes developers stay at work extra longer past midnight to implement that extra rocket launcher effect to stand out from the competition.
Then the market judges you on purely subjective measures. You can't lock yourself into a market like MS Office or Windows would. It doesn't even matter if you are technically the most advanced. As a game developer you are fighting for gamers attention. This is why you see games that are mostly sequels and based on established IP.
Then again these challanges are the reason I'm a game developer. Mr.Blow does point out a good deal of inneficient practices in the industry.
This should be seen as a call to arms for middle ware vendors and ISVs. Whenever there is a problem there is a buisness plan!
That's only 7 years. In the 7 years I've been in the business, I've become a certifiable 'old man'. That may sound nutty, but our industry moves so fast, it's perfectly sane. An in that 7 years, things have shifted massively.
When I first started, I worked on a project with a budget of about 2.5-3 million $. At the time, that was considered a pretty large amount. Our team was about 20 people, mostly rookies of 1 year (or less) experience, with 5-6 'old salt' types. This was a PC title at the very earliest edge of 3d acceleration. The voodoo 1 was barely out there. Use of floating point 3d math was finally starting to be possible. Our target for 'great sales'? 200,000. If we sold 100,000 it would be considered 'good'. 200,000 would be fantabulous. 300,000 and up would be massive wild success.
50 million. The average game that gets greenlit these days has a budget of 12 million or more. When you pitch a AAA title to a publisher the magic number is '1 million units'. This is of course an insane number that no one realistically expects to hit (especially the poor developers themselves). But the expectation of the top-end people is 'if we don't realistically think this can sell 1 million units, why are we considering it'?
You know what -hasn't- changed in this time? Selling prices. Games still retail for $40-50.
Yet budgets have quadrupled or worse. Technology has leaped forward by a LEAST 10x in capabilities. We went from the Voodoo 1 (cool! hardware rasterizing!) to the Voodoo 2 (awesome! really -fast- hardware rasterizing with multitexturing!) to the TNT (WOO! Even -faster- hardware rasterizing with multitexturing!) to the Geforce (Yay, no we've got T&L) to the Geforce 2 (Hmm, T&L plus a complex layer of vertex shaders) to the postmodern Geforce 4+ cards (ummm, dang, 4+ versions of pixel shaders now with a dump truck full of crazy, complex techniques which all the artists and designers and producers all have a hardon over). Ah, we've also got 20x the memory available and 30x the processor power. Can't ship anything without an ultramodern physics engine, or an endless streaming arbitrary polygon-soup world now can we?
And to top it all off, the trend in actual sales is : instead of a largish array of semi-successful to successful games, we now have a huge bundle of big-but-unsuccessful games and a small handful of monster selling uber titles. With very very very little in between.
Publishers now aren't willing to commit to something unless they think it'll sell a gajillion units. But of course, selling a gajillion units means having lots and lots and lots of risky and expensive features. So doing these big payoff games is a big gamble.
This 'Inflationary Period' (to borrow a term from cosmology) has resulted in a radically different landscape. Programmers balk (for good reason) at the design requirements necessary to make a competitive game. I have the privelege of working with some very smart people even 'older' than I am. One of them once said to me : 'Practically everything we do is worthy of a PH.d thesis'. And he is right. You can't -not- push the already ludicrous technology barrier with a new title, otherwise you'll be putting forward a design with limited sales appeal.
It's an ugly ugly situation. Where I work, we are to this very day struggling with coming up with a design for our next project (one of several) that will satisfy these myriad goals. Everyone is so incredibly smart and dedicated, but it seems to me that we're very fast approaching some sort of upper-bound on complexity.
I don't know where it is going to end, but at the moment, you can be damn sure that the days of the garage-developer are over. Technology has accelerated too fast.
Besides this, many people have ideas that have already been thought of but weren't done because they just aren't feasible to do or don't add to the fun in any way.
I think the problem isn't a lack of programmers, but that the design isn't focussed enough that the programmers aren't wasting their time on stuff that makes no difference to the gameplay. Some of this is attributable to the publisher who wants some new feature to advertise (realtime wart-growing!), or some overly ambitious designer that wants things that add nothing to the gaming experience (did MGS 2 really have ice cubes you could watch melt? If so, then WHY?).
I really think that every designer should be made to play Super Mario 64 and Tetris. SM64 was huge, and Tetris was small, but both are very tightly focussed on the things that make the game FUN.
"But I trust in the people's capacity for reflection, rage and rebellion." -Oscar Olivera
"that we have a perpetual shortage of qualified people in the industry."
This is funny. A few years ago, after working on successful but boring software projects for the past ten years, I decided that I wanted to work in the game industry. I have no debt, and was willing to take a pay cut. I live in San Diego, home of a number of game companies, EA, Sony, etc. I figured it wouldn't be too difficult to get myself at least an entry level position with 10-years experience, just to learn the ropes. Nobody seemed willing to hire someone that didn't have several previously delivered games under their belt, despite a number of other successful consumer products and happy customers. I had sent resumes to all the companies in the area, as well as working briefly with a "game headhunter" which didn't work out as well. After roughly six months of trying, I gave up, and went back to working on my boring jobs. I'm guessing that the writer of the above quote isn't all that tied into the needs of the industry.
WWJD -- What Would Jimi Do?
(Smash amp, burn guitar, take home the groupies)
That's a common perception from those outside of the entertainment industry. There are those 'stars' in the game industry, just as there are in the movie industry, who really do think that. One of the plain facts is that modern games take a lot of intellectual work, much more than optimizing SQL queries, putting components on forms, or making two computers talk to each other. It's no different than how some professors look down at some software developers. While it does take skill to do it, you aren't really pushing every neuron in your brain to put out form-based apps or SQL-based systems.
Regarding the amount of learning that has to take place:
Of the programmers on my team, 4 (including myself) have masters degrees and two have bachelors degrees. Every week I find myself reading several papers from journals and conference proceedings. In contrast, two of my brothers are also programmers. One does POS software for a nationwide company, another works for a small company with photo processing software. Both have seen the things I do at work, and I've seen theirs. Both have told me that they couldn't handle my job, but I know I could do either of theirs. One of them has had to read a few journals and articles, the other hasn't read any since he earned his bachelors degree almost a decade ago. One of them works with mostly BS degree or no degree, the other works with entirely BS degree and one MS degree people. As for me, I've thought about going back and getting another bachelors degree in math just to review some of the advanced topics.
Neither of my brothers, both competent programmers, can understand the math it takes in writing game graphics engines. Do you understand the math involved in manipulating manifold surfaces, or self-shadowing techniques? Perhaps you can explain to the crowd how to make a 3D model look like it is breathing? Or maybe implement a system to give models joints at hips, knees, ankles, and toes, and make them realistically move, jump, walk, crawl, or stand still, based only on a direction and speed? How about converting between 4x4 matrix form, and Euler angles, and quats? Can you even understand a number that has 1 real part and 3 imaginary numbers, [w, xi, yj, zk], and has no real-world analogue? How about pathfinding; Since you play games, can you explain or implement 3 of the pathfinding techniques you've seen? Maybe machine learning is your forte; Can you implement at least 2 machine learning methods, such as RBF networks or backprop neural networks? [Incidentally, while seldom used, both work well in games since there is practically no cost to use them.] How about cheat-resistant networking; Do you know how to tell the difference between a forged packet and a regular one? How about how to properly get around a NAT device? Since TCP is too slow, do you know how to deal with out-of-order UDP data? Or keep clients in sync when they are missing critical information? I've only met a few non-game programmers who could do all of these, but EVERY PERSON ON MY TEAM knows how to do ALL these. But even then, I can still do most of the things you probably do as a programmer. I frequently help my brothers out when we talk about difficult issues they are fighting in their own projects.
Again, in comparison with my brothers. In their environments, they plan

Games are very complex pieces of software these days for sure. Graphics, audio, networking, even UI is a big deal. Just getting something working is only the beginning. Then comes the real work in making your game engines perform such that you are hitting your framerates in every area of the game.
It used to be if your main loop was hitting your framerate, you were done. This is because you did all of your I/O up front (the loading screen). Your user input was always polled each frame, so unnecessary state changes that could possibly disrupt your performance were minimal. Largely it was your graphics theory knowledge that made or break your engine.
Nowadays it is becoming more non-deterministic due to other forms of disruptive state changes. Graphics have become more complex and networking creates state changes that often don't happen within one frame (e.g. picking up an item in Quake 3 requires the server to acknowledge this).
People complain about why studios ask for at least 5 years of experience and on top of that ask for prior experience with a particular console. Getting something working fast isn't the goal. It's getting it working correctly.
How relationships with publishers changes priorities is an entirely different discussion, however...
You should never take life too seriously - You'll never get out of it alive.
Every year or so I buy a game that consists of 90% 3D fluff
The game industry looks like the equivalant of the comic book industry in the eary 90s, lots of eye-candy, gimmick covers, etc and little substance.
I think the way this works is this: there's three types of games- those with fluff, those with substance, and those with fluff and substance (and gradients inbetween of course). Substance, by itself, does not sell.
The thing about substance or gameplay is that it requires a certain amount of attention that cannot be extracted from an audience until they have bought the product and invested some amount of minutes or hours into it. The sure-fire way to get that investment is to attract the eye- visuals can transmit much more information about something much faster than sound or text, so discerning quality of visuals is easy for nearly anyone. There is no shorthand to communicate gameplay other than simply playing the game, though screenshots and videos and short text descriptions may at least indicate what is to be expected.
If I'm going to play a crappy game, I'd rather play a crappy game that looks good than the alternative- and the same goes for other visual media.
An addition to that last statement is that there are a lot of people for which style is substance. The obvious ones are artists, or people with ambitions in that direction or simply an appreciation for it- playing something with really cool level and character design and etc. is the main thing while the story and interface should drive it along- if they're really good, that's a great bonus. Bad story isn't really a showstopper, but bad interface is - so I don't mind seeing the 'cookie cutter' approach get used there because I'd rather not every game try to reinvent the wheel when I just want to move the camera/character/units around.
Do you know Counter-Strike? Its a mod. Do you know DoD? Its a mod. Actually some very interesting games comes as a devirative work of other game. That safe a lot of work, whatever can be shared, dont need to be recreated (the engine, textures, sounds, menus, etc...) and you have instantly a lot of users.
So you make a tiny mod for Half-Life, and you have a 1 millon potentian userbase. Cool or not?
Making mods shortcut the problem of very very long development process.

Recently a quake guru (FrikaC) has make a Tetris clone in only 2 hours of work. You can download a stand-alone version here:

-Woof woof woof!
We would much rather have that manpower spent to make the system compile programs quickly, or generate efficient code,
Bingo, I think the future of mmg's depends on this. People increasingly will want more variation in gameplay. Concepts like an Architecture Generation Engine (AGE) would benefit greatly from this. An AGE makes a multiplayer map/scenario different every time you play it, so you have to adapt all the time. The ability to randomly generate and compile the new map very quickly, is very important. This for me is the neatest thing in gaming going on right now. Great article!
