Maxis Developer on Linux Game Porting
friedmud wrote in to tell us about a comment from a Maxis developer, Don Hopkins, who did a partial linux port of "The Sims". You can find his post here (3rd one down, comment from Don Hopkins titled "Reality check from a game developer") in a LinuxGames.com forum. I don't know if I agree with his assertion that Wine is the best way to have games happen on Linux but his comments on the economics of Linux games development and especially the costs of keeping versions concurrent on multiple platforms are insightful.
I think the best current approach involves Java, which can be either natively compiled (gcc 3.0) or run on a VM (JDK 1.4 should be quite good). Check out Arkanae for an early preview. :-)

Having multiple target platforms is a serious headache, and Linux just isn't a big enough market. Most linux users are used to getting their software for free anyway, and probably have the technical savvy to score free versions of any software released. While I'm sure that there are plenty of honest people out there, the fact is that there are very few people who are going to pay for linux games.
Also considering the generally degraded performance of games under linux and the continued acceptance of DirectX as the standard for graphics, all make Linux development difficult.
I read recently that id doesn't want to release their next product under linux (historically they have been pretty good about that stuff) because its a support nightmare, and just really doesn't bring in that much revenue.
I think in order to start getting more native Linux games, Linux needs to prove itself as a consumer OS first. Once Linux starts to satisfy peoples needs easily (thats so important) then i think more people will start moving over, and once they do, then the linux games will start rolling in.
I believe some of the problems lie in the way a multiplatform library works. For games, if SDL isn't as fast on Windows as DirectX, why should it be used? I know its a bad example, because I think that SDL actually routes down to DirectX on Windows. Remember, users come before developers...
But what about a UI library that doesn't draw the controls the same as the user's operating system? Look at Photoshop for Windows.. it looks like I'm using a Mac. I don't want that! I want an application that looks and feels like what I normally use. The best libraries will work like that, even though they have a cross-platform API. Linux versions will have the window manager look and feel. Mac versions will look like a Mac application.
RealBasic for Mac does this pretty well. Using a single source tree, RealBasic will compile for both Mac and Windows. The Mac apps look like Mac apps, and the Windows apps look like Windows apps. That transparency is what will win.
Of course, to make it easier for the developer can be a good thing. But to give the user a better experience is more important. Because if a user doesn't like your product, why bother?

So let me get this straight. The highest modded post from yesterday's story is copied to another forum, and it makes today's news?
Anyone remember when Windows 95 came out originally? It had no games, or at least the ones it did have sucked big time. Everyone moaned that Windows gaming would never take off because dos games were faster, and more dedicated.
And now everyone uses Windows.
Why?
Because it was still possible to play at least some dos games under Windows (because it was built on dos), and with for a bit of hassle, Windows would close, your game would run, you finish your game and windows would reboot.
Yeah, it wasn't neat, but it let people move to Windows 95 and still play their dos games. Once the user base was large enough, native games became available.
My point is, the argument against Wine is exactly the same.What I want to be able to tell people is
"Yeah, you CAN play all your existing Windows games under Linux! Try it and see! It's SOOOOO much better than Windows!!!".
Y'see, if we could get people using Linux more, the user base grows. Then it becomes more feasible to make native Linux games. Then the user base grows some more... See what I'm getting at?
If wine can play all windows games, we can get all those game loving people who won't try Linux because it hasn't got any games to try it and love it too.
One of the things I didn't see mentioned is that a lot of developers are writing for the console only.
c old-dead-hands crowd clamors for support and then whines when they can't get it.
Consoles have a lot of advantages. They are stable same-same environments. Not a lot of variance, since there is only one manufacturer for each one. There have been some companies that have questioned making games for PCs entirely becuase of the wide variance in the hardware, let alone the operating system.
Many companies make two versions now, one for their console-of-choice and another for Windows/Intel PC platform.
Guess which one is the support nightmare. Pretty easy when you have to support several different video card manufacturers, even ones that don't exsist any more like VooDoo. Yet, the small, vocal, they-will-get-my-VooDoo-when-they-pry-it-from-my-
Different versions of Windows, cheap, God-awful systems from Best Buy and Circuit City, poor white box mail order, you name it, and its a problem on the PC platform.
So, is it a Windows vs Linux thing? Not really. Unless Linux becomes the dominant desktop environment, or at lest has double digit percentage numbers, its a useless question. Developers don't REALLY want to develop on the PC to begin with because of the high support cost, and they are certainly NOT going to develop for a low desktop marketshare OS like Linux.
Think about this anyway: If they did, they would only support it on Red Hat anyway,(market share and mind share again) and then you would bitch about that. This community will only be happy if there are NATIVE Linux games that work on every distro. Ain't gonna happen. Be happy there is still a market for PC games at all.
so i think the sims might lure them away from Windows.
IMHO, no game is going to lure people away from Windows. Think about it:
There is a user that runs windows and buys games that run on windows. Now, one game is ported to Linux, but it also runs on windows! Why would they switch? There's no need, that game already runs on windows, as does every other game they own, and the overwhelming majority of games due to come out.
Really, what is so *great* about Linux that will lure the gamer from windows? The lack of games? The lack of driver support? Or maybe the fact that it's completely different than everything they know?
Now, if the Sims 2 came out *only* for Linux, you might have something!
Where are we going and why am I in this handbasket?
Linux is not worth it. Not 5 years ago, not today, not tomorrow, not a year from now.
People said the same about windows games. "Why develop for Windows when everyone has DOS?". Well, corporate IT was moving towards windows, so the savvier game developers saw that people would soon have windows everywhere - and if there's one thing that people always do, it's play games when they should be working. Now corporate IT (at least in here in Europe and (according to reports) in Asia) is moving toward linux on the desktop and server.
OpenGL develops slowly and requires proprietary extensions for the newest video cards.
OpenGL development did slow down a bit. It's speeding up again now, thanks largely to Mac OS X. There may sometimes be extensions, but that's still better than the whole bloody thing being proprietary and at the whim of MS, like D3D is. There's a well-defined process for folding such extensions into future revisions of the OpenGL standard. OpenGL was designed to be extensible.
Also, the Direct* APIs are a bitch unless you code in MS-mutilated C++ - OpenGL has well-defined, easy to use, pure C and fortran bindings, as well as decent bindings for many other languages. - That's one of the reasons OpenGL is used for high-end applications, like CAD and scientific and engineering visualisation (my specialty). DirectX truly, deeply sucks for anything like that. OpenGL is also designed for very high poly-count stuff encountered in visualisation. OpenGL on linux is being developed enthusiastically, from the industrial side - visualisation front ends for $50000 numerical simulation software that used to run on SGI IRIX systems are now being run on Linux boxes. OpenGL isn't going to fade into obscurity anytime soon - the profits from a couple of licenses for the sort of software that really uses OpenGL can outweigh the profits from the sales of hundreds of thousands of copies of weenie windows games.
Choice of masters is not freedom.
That's really only true for Valve (Half-Life, Half-Life GOTY, Half-Life Gold, Half-Life Platinum, Half-Life You'll Buy This Too, Even Though It's The Same As What You Already Have, etc). Most other publishers might make a GOTY edition and leave it at that. However, if by wringing "every penny out of what they have" you mean making sequel after sequel, I don't see what your argument is. Especially since the good sequels do add innovative new features or items (let's ignore the Tomb Raider franchise, shall we?). As far as not porting to other platforms, I don't see how that's really an issue. Most game houses don't seem to have problems porting back and forth from consoles (PS2, PSX mainly) and Windows. They're not going to bother with Linux because it's such a marginal market. There's no money there, so why bother? And ignoring a valueless (monetarily) market is not going to kill a company. In fact, porting to that market just might kill them instead.
Note that
Because we all know that only poor, stupid programmers use IDEs ... (btw, all the Visual Studio compilers (for C++, VB, C#, Jscript, and so on) can be used strictly from the commandline, using makefiles or build scripts, and you can use any editor you want to write the code they compile -- vim, emacs, notepad, Source Insight, Visual Studio, or whatever)
Red Herring. It's not a University's job to produce automaton that can write a makefile or compile the latest 'sploit by hand. If that's what you expect from a CS program, you'd do better to save money and go to a tech school (or alternatively, save money buy hiring a student out of a tech school). A properly educated CS student may not know how to write a makefile or use gcc from the commandline right out of college, but I can guarantee you that s/he will be able to learn how to do that quicker than your average self-taught or tech school programmer can learn to analyze the performance considerations of various search algorithms (for instance).
