Slashdot Mirror

A recently discovered hole in Valve's API allowed observers to generate extremely precise and publicly accessible data for the total number of players for thousands of Steam games. While Valve has now closed this inadvertent data leak, Ars can still provide the data it revealed as a historical record of the aggregate popularity of a large portion of the Steam library. From the report: The new data derivation method, as ably explained in a Medium post from The End Is Nigh developer Tyler Glaiel, centers on the percentage of players who have accomplished developer-defined Achievements associated with many games on the service. On the Steam web site, that data appears rounded to two decimal places. In the Steam API, however, the Achievement percentages were, until recently, provided to an extremely precise 16 decimal places.

This added precision means that many Achievement percentages can only be factored into specific whole numbers. (This is useful since each game's player count must be a whole number.) With multiple Achievements to check against, it's possible to find a common denominator that works for all the percentages with high reliability. This process allows for extremely accurate reverse engineering of the denominator representing the total player base for an Achievement percentage. As Glaiel points out, for instance, an Achievement earned by 0.012782207690179348 percent of players on his game translates precisely to 8 players out of 62,587 without any rounding necessary (once some vagaries of floating point representation are ironed out). Ars has shared the Achievement-derived player numbers in their report; there's also a handy CSV file. Some of the titles with the most total unique players include Team Fortress 2 (50,191,347 player estimate), Counter-Strike: Global Offensive (46,305,966 player estimate), PLAYERUNKNOWN'S BATTLEGROUNDS (36,604,134 player estimate), Unturned (27,381,399 player estimate), and Left 4 Dead 2 (23,143,723 player estimate).

trawg writes: "Programming legend Michael Abrash has announced that he has joined the Oculus team to work on the Rift VR headset as Chief Scientist, and will be once again working with John Carmack to bring VR to life. His post covers a lot of ground, including the history of his quest for VR, and ends with his explanation of why he thinks the Facebook acquisition is ultimately a good thing — they have the engineering, resources and long-term commitment 'to solve the hard problems of VR.'" Abrash has long maintained a blog about VR tech — it's worth reading if the subject matter interests you.

An anonymous reader writes "Stack Overflow co-founder Jeff Atwood has posted about how much progress we've made toward commercially viable virtual reality gaming — and how far we have to go. The Oculus Rift headset is technologically brilliant compared to anything we'd have before, but Atwood says there are still a number of problems to solve. Quoting: 'It's a big commitment to strap a giant, heavy device on your face with 3+ cables to your PC. You don't just casually fire up a VR experience. ... Demos are great, but there aren't many games in the Steam Store that support VR today, and the ones that do support VR can feel like artificially tacked on novelty experiences. I did try Surgeon Simulator 2013 which was satisfyingly hilarious. ... VR is a surprisingly anti-social hobby, even by gamer standards, which are, uh low. Let me tell you, nothing is quite as boring as watching another person sit down, strap on a headset, and have an extended VR "experience". I'm stifling a yawn just thinking about it. ... Wearing a good VR headset makes you suddenly realize how many other systems you need to add to the mix to get a truly great VR experience: headphones and awesome positional audio, some way of tracking your hand positions, perhaps an omnidirectional treadmill, and as we see with the Crystal Cove prototype, an external Kinect style camera to track your head position at absolute minimum.' Atwood also links to Michael Abrash's VR blog, which is satisfyingly technical for those interested in the hardware and software problems of VR."

An anonymous reader writes "The itinerary for Steam Dev Days 2014 lists two talks by Valve's internal virtual and augmented reality researchers, Michael Abrash and Joe Ludwig. Abrash's talk, titled 'What VR Could, Should, and Almost Certainly Will Be within Two Years' will feature a demonstration of Valve's secret prototype VR headset that is 'capable of stunning experiences.' Ludwig's talk 'Virtual Reality and Steam' will discuss how Valve will be adapting Steam to VR to 'support and promote Virtual Reality games.' Rift inventor and Oculus co-founder Palmer Luckey will also be taking to the stage at Steam Dev Days to speak on best-practice for VR development." There's a hint that they might be showing off a head mounted display featuring a low persistence display, which would be great news for those of us that get the urge to hurl when playing Doom on a conventional display. If you missed it you might want to check out the slides and notes (PDF) from Michael Abrash's GDC2013 talk on VR.

sl4shd0rk writes "Valve has finally released Steam for Linux. Although some of the 57 games listed on the Linux Steam site are previously released from the Humble Bundles, there are others which should provide adequate entertainment for anyone bored with the HB games. Among the games listed, many at deep discounts of 50%-75% off, are HalfLife, CounterStrke Source and Serious Sam 3. Hopefully Valve will keep the ports coming as rumor has it that Left 4 Dead had been ported at least for developers."

An anonymous reader writes "In the third post to the new Valve Linux Blog, the Linux team has announced that starting next week they will begin their internal beta, with an external beta of 1000 users to begin mid 'some time in October.' There will be an external beta sign up page made available 'soon' according to the blog."

ProbablyJoe writes "The long awaited Source engine remake of the Valve's original Half Life has finally been released. The initial release only includes the story up until Xen, but the developers say they'll be adding the rest of the story, along with an online multiplayer Deathmatch mode, soon. The game is available to download for free, and only requires players to install the Source SDK (included with all Source games, or a free download). The highly anticipated release has also caused a huge amount of traffic for any servers hosting the files, with GameFront, GameUpdates, and Black Mesa's own CDN brought down within minutes of the release. The project has also been approved by Steam's Greenlight program, and will hopefully be available through Steam soon, though no timeframe has been given."

redletterdave writes "Valve is reportedly interested in building hardware. The Bellevue, Wash.-based software developer added a job posting to its site on Tuesday morning for an industrial designer. We're frustrated by the lack of innovation in the computer hardware space though, so we're jumping in,' the posting said. 'Even basic input, the keyboard and mouse, haven’t really changed in any meaningful way over the years. There's a real void in the marketplace, and opportunities to create compelling user experiences are being overlooked.'"

New submitter nschubach writes in with an update on Valve's progress porting one of their games to GNU/Linux. From the article: "One factor in creating a good gaming experience is throughput. This post discusses some of what we've learned about the performance of our games running on Linux. ... After this work, Left 4 Dead 2 is running at 315 FPS on Linux. That the Linux version runs faster than the Windows version (270.6) seems a little counter-intuitive, given the greater amount of time we have spent on the Windows version. However, it does speak to the underlying efficiency of the kernel and OpenGL. Interestingly, in the process of working with hardware vendors we also sped up the OpenGL implementation on Windows. Left 4 Dead 2 is now running at 303.4 FPS with that configuration." nschubach adds "It seems there are good things coming out of this for both Operating Systems!"

New submitter oakgrove writes "Valve Software confirmed today in a new blog devoted specifically to Steam on Linux (called Steam'd Penguins) that for more than a year, a Steam client has been in the works for Ubuntu Linux 12.04. 'We've made good progress this year and now have the Steam client running on Ubuntu with all major features available. We're still giving attention and effort to minor features but it's a good experience at the moment. In the near future, we will be setting up an internal beta focusing on the auto-update experience and compatibility testing.' The blog post also says that a working port of Left 4 Dead 2 is currently playable, and that their goal is to bring performance in line with the Windows version."

New submitter Canazza writes "According to Develop, 'PC games giant Valve wants to "invent whole new gaming experiences" and is looking for people to help create new hardware, the Washington studio has confirmed. Off the back of a wave of speculation that the studio is building its own games console – a rumour which Valve has not specifically denied – the company now appears to be increasing capacity of its hardware development division.' Is Valve designing a new console? Or is this an expansion of its biometric controls research? Either way, something big is going down at Valve."

Following up on news from earlier this week that Valve made Team Fortress 2 free-to-play, we now get word that the Source engine SDK will be free to all as well. Quoting Rock, Paper, Shotgun: "The Source Software Development Kit, for those of you who've never clicked the Tools tab in Steam, contains everything you'd need to make a mod, except for personal ambition. It has everything from the infamous Valve Hammer Editor to Face Posers and Model Viewers. At the moment, to gain access to the Source SDK you have to purchase a Source based game such as Half Life 2, or as the official website states, Team Fortress 2. Which is of course now free. [Valve's Robin Walker said], 'We are in the process of getting it all done. It’s a bit messy because we have multiple versions of the SDK, and there’s some dependencies we need to shake out. But yes, the gist of it is that we’re just going to go ahead and make the Source SDK freely available.'"

Valve has released a beta version of their authoring tools for Left 4 Dead. The tools will allow you to "create your own campaign maps, character skins, 3D models, sound effects, and music and load them into the game." The kit includes a level editor and command-line compiling utilities, as well as example maps, props, infected, and explosives. It also brings plugins for a 3D modeling program called SketchUp. Valve has updated their development wiki to go along with the release.

Ant writes "Edge Online has a six-page article titled "The Age of Steam" about Steam's history that begins: 'The name could hardly be more appropriate. Just as railroads swept the US, leaving in their wake a west that was significantly less wild, so has Valve's Steam client spread across the PC, centralising, simplifying and consolidating. What started as a way of administering updates has become a delivery platform so powerful that it has threatened to render even the big publishers' alternatives obsolete, an online community so well-supported that it sets standards even for those found on consoles, and a no-fiddling environment that allows your games, settings and saves to follow you from one PC to the next every time you log in. Looking back, such success seems inevitable, but in reality Steam was far from an obvious idea. Creator Valve was a developer, not a publisher or distributor, and the service's opening months were marred by bottlenecks and a frustrating online registration experiment. More interesting than the triumph, then, is the journey: what has made Steam such a powerful platform? Which forces shape its evolution? And how can it rewire not just the PC market, but the way that games themselves are developed?'"

SheeEttin writes "If you've been longing to play games from Steam on your Linux machine, you may not have to wait much longer — the Left 4 Dead demo includes some Linux libraries, in particular, one named 'steamclient_linux.so.' While the game's full release does not include these libraries, their apparently accidental inclusion in the demo suggests that Steam games will have native Linux clients in the near future. (A job listing at Valve looking for someone whose responsibilities would include 'Port[ing] Windows-based games to the Linux platform' would seem to support this.) The libraries also include several strings nonessential to a pure server, including references to forgotten passwords. Hopefully, this indicates that at least some Valve-affiliated games will have native Linux clients."

Martin Bozic writes "Valve is apparently looking for senior engineers to port games to Linux. They have an ad up on the official site looking for a Senior Software Engineer with experience in 'systems engineering designing and developing communications software and hardware solutions including resolving problems surrounding real-time and non real time PC- based systems using C++ and network programming algorithms and their interaction with physical devices.' One of the lines under the job description is the simple statement: 'Port Windows-based games to the Linux platform.'" No reason to get excited about this before they make an official announcement; while this may eventually mean Half-Life 2 running under Linux, they may just want penguin-based folks to play Peggle.

Via Gamasutra, the news that Valve has opened a Developer Community Wiki. From the post: "The system is intended to be a pool of knowledge that mod authors can contribute to, as well as consult for advice on how to use the robust Source engine. The Community is built using MediaWiki, an open-source GNU tool for allowing entries and posts to be edited and refined by anyone with an account. The same technology powers the popular Wikipedia, an online encyclopedia."

ShamusMcGee writes "Valve today announced the U.S. Federal District Court in Seattle, WA granted its motion for summary judgment on the matters of Cyber Café Rights and Contractual Limitation of Liability in its copyright infringement suit with Sierra/Vivendi Universal Games." From the judgement: "...based on the undisputed facts and applicable law, Sierra/Vivendi, and their affiliates, are not authorized to distribute (directly or indirectly) Valve games through cyber-cafés to end-users for pay-for-play activities pursuant to the parties' 2001 Agreement."

sinner0423 writes "Due to recent complaints on several forums, Steampowered announced they are working on a fix to this stuttering problem in Half Life 2. Usually, a game bug isn't news-worthy, but the sporadic nature of this bug makes me wonder - who else has problems with HL2 pausing/skipping? This site outlines the problem certain users are having in a very clear & concise manner, and also includes some stopgap solutions from Erik Johnson & other Valve employees."

Thomas Scovell writes "After over half a decade of development, stolen source code debacle, a promised deadline that was missed by a year, and a feud between the developer and the publisher that is still in court, Half-Life 2 has finally started to activate for those who have purchased online via Steam online or who grabbed the boxed version at the retailers that let it slip early. Go play!" Reviews are available via Gamespot, Gamespy, HomeLAN Fed, and IGN.

aWalrus writes "The long wait for Half Life 2 and bundled games through Valve's online distribution system, Steam, ends today. Steam news reports that Half life 2 packages will be available at 11 am PST. With HL2 still trapped in publisher approval limbo, these packages don't have the game yet (available upon products' release), but they do have Counter Strike:Source. This could be a good bargaining chip for Valve and a boost to Steam distribution."

fistfullast33l writes "Valve has announced via Steam that a Beta version will be launched for Counter-Strike: Source, the multiplayer counter-terrorism mod that will now be updated for release with the Half-Life 2 powering Source engine. It is expected to be kicked off around late summer. Apparently: 'The beta will first be open to subscribers of the Valve Cyber Café Program, and then extended to owners of Counter-Strike: Condition Zero.' Seems like a good time to find out where the nearest gaming parlor is." This move is interesting in light of allegations of Valve bullying cybercafes - we also recently covered the South Korean unveiling of Counter-Strike: Source over at Slashdot Games.

Thanks to CS-Nation for its discussion of the first public showing of Valve's team-based FPS Counter-Strike: Source, including new screenshots and videos, as "the first playable exhibition of it [was held] this weekend in Seoul, Korea." An earlier CS-Nation news story has comments from an attendee, who suggests: "It isn't really different from the way you would feel while you're playing current CS. New physics and graphics are obviously improved, but it wasn't really enough to make me shock in awe." However, he does argue: "The graphics, of course, [are] absolutely excellent. I think the new de_dust2 is the map that can show the real power of [Half-Life 2 engine] Source."

Thanks to Half-Life 2 Fallout for its fan-written feature discussing the content of Valve's Source videogame engine, as used for Half-Life 2. The piece explains: "The Source engine is not just a 3D engine (in the sense it's not just a renderer) -- it contains many different modules that are all brought together into one package", and tries to clarify discussion on subjects as diverse as lighting ("Something that has caused confusion in the past is 'dynamic lights' [in the Source engine].... All a light has to be in order for it to be qualified as dynamic is to be able to move and have changeable attributes.... It doesn't mean that it will [necessarily] cast real time shadows like in Doom 3 or Unreal Engine 3.0"), and in-game water ("When Valve say the water is physically simulated, they mean objects have buoyancy. They don't mean the Source engine has fluid dynamics.")

Thanks to EvilAvatar for pointing to a Seattle Post-Intelligencer article discussing how gaming sequels tower above most movie sequels in terms of desirability and quality. The piece argues of movies: "Sequels suck, right? For every 'Godfather 2' and 'Aliens' there are hundreds of horrendous rehashes clogging the video store shelves. Hollywood wants your money; quality control be damned", before contrasting them with games: "Fans chomp at the bit for a few screenshots from the next installment of beloved games such as 'Half-Life' and 'Halo.' When the games arrive they rarely disappoint. Gaming franchises get better and better while their celluloid cousins go straight to video." Valve's Gabe Newell also comments on feedback for sequels: "We are super-involved in the community that has sprung up around our games. Whether through e-mail, the forums, the fan sites, or calling my house at 3 a.m. in the morning, we have a pretty good idea what they are thinking. And it absolutely factors into our decisions."

daitengu writes "After almost a year and a half of 'It'll be out soon', Valve Software has finally released Counter-Strike: Condition Zero. It is available on Steam for the low-low price of $29.95 or, rumor has it, you'll be able to buy it in stores today or tomorrow. Counter-Strike is the world's most popular online First Person shooter, and Condition Zero brings updated maps, skins, and graphics to the game, as well as a single-player mode. It also brings what some reviews have claimed as one of the best AI they've seen." The submitter continues: "If this game was released 9 months to a year ago like Valve was promising, I may have invested the $30 or $40 to buy it. Now, however, It's just not worth it to me." Does CS:CZ pique your interest at all?

Thanks to ShackNews for their updated report from Valve boss Gabe Newell regarding Thursday's leak of the Half-Life 2 source code. He says: "We're still finding machines internally that have been compromised" in relation to the "infiltration of our network" that led to the code leak, and warns that other developers may also be in danger: "There's anecdotal evidence that other game developers have been targeted by whoever attacked us." But he ends with a hopeful appeal to those who've been helping Valve hunt down the culprits online: "I've been fielding calls from the mainstream non-games, non-technical press all day. Hopefully they will get to report shortly what a mistake it is to piss off a whole bunch of gamers and get them hunting you around the Internet."

jvm writes "If you're a gamer with a pulse, you've probably heard about the impending release of Valve's Half-Life 2. As a gamer and a Linux user, I always get a little stirred up about the whole Half-Life situation, where we have a dedicated server but no client. So here's my reflection on the sad situation, past and present. How will the rest of the Linux gaming community react to the release of Half-Life 2? Boot into Windows? Wait for WINE or WineX support? Get the Xbox version? With so many Half-Life servers running on Linux, will the same be true for Half-Life 2?"

Latent IT writes "If you're into games, and unless you've been living under a rock for the past few days, you've heard a bit of a rumble from Valve on the relative quality of ATI vs. NVIDIA cards. Starting with articles like this one (previously reported), Valve told the world that the ATI 9800 Pro was nearly three times faster in some cases than the formerly competitive NVIDIA offering, the 5900 Ultra. Curiously, this happened at an ATI sponsored event, "Shader Day". But the story hasn't stopped there. NVidia released this response, essentially claiming that their new drivers, that were available to Valve at the time of their press conference, would make for vast, legitimate performance improvements. An interview with Massive, the creators of the Aquamark 3d benchmark, seems to confirm this opinion - that the NV3x chipset wasn't designed around any certain API very well, and the drivers are critical in achieving good performance. Anandtech writes here about the restrictions Valve placed on what benchmarks could be run. However, the key to this whole story may be this: an article, which I haven't seen get much coverage in all this, seems to make everything a little clearer - Valve stated that their OEM bundling deal with ATI came from the fact that ATI's cards were so superior, and that they were "performance enthusiasts". However, if the Inquirer is to be believed, the bundling deal was a result of an outright auction, on what will probably be the most popular game of the year. Which year that might be, is another issue altogether. Whatever happened to just making hardware, and making games?"

Thanks to Eurogamer.net for their preview of Vampire:The Masquerade - Bloodlines, with new info and screenshots on the FPS/RPG hybrid from Troika, the creators of Fallout and Arcanum, and the first announced title apart from Half-Life 2 to use Valve's Source Engine. According to a Troika representative, "Bloodlines is the first game to combine the classic RPG feel with a first person shooter engine", and Eurogamer also single out the return of the classic RPG 'conversation tree' as providing fresh gameplay ideas: "For example, your character may have excellent seduction skills, or be part of a specific clan that allows you to ask questions or offer responses otherwise unavailable to you, and these 'special' branches of the conversation will be shown in a different font to indicate this."

Allen Varney writes "Why wait for Half-Life 2 when you can wait instead for Half-Life 2D? 'Codename: Gordon' is a free, fan-produced jump'n'run side-scroller adapted from the original Half-Life. It'll be done in a month, but for now there's screenshots and a two-minute gameplay video."

suineg writes "Gabe Newell, Valve's main man, has commented on Half-Life 2 and anti-aliasing problems with DX9 cards over at HalfLife2.net: '[The current problems] ...will look like a bright or dark line on the edge of a polygon. This is not a new problem. Artifacts may show up more frequently in Half-Life 2 simply because we've eliminated lots of other artifacts, and because we have a lot of variation in scene lighting due to our art direction.'" As far as solutions go, Newell has some: "ATI has supported... [the centroid work-around] form of anti-aliasing for the 9000 series... [as for] NVIDIA's [hardware], that doesn't support centroid sampling... you trade off some pixel shader bandwidth to clamp the texture coordinates."

scottcha+4 writes "When it was released in November 1998, Half-Life redefined the action gaming genre by combining fast-paced action and an intelligent, intense story. Players quickly began clamoring for a sequel, but developer Valve Software responded with silence. Five years later, the call for that sequel is as loud as ever. Get the details via this CNN story." The CNN coverage has a couple of amazing-looking screenshots and some brief details, but there's going to be a whole lot more after magazines like this arrive in stores and the press embargo is fully lifted.

Laurens Simonis writes "Yesterday, the Dutch ISP Planet Internet introduced a games subscription service. For a small monthly fee, about $10, you get unlimited access to a growing list of (sort-of) current games which you can legally download from them. Currently, you can pick from 20 titles including Tomb Raider Chronicles, Alone in the Dark: The New Nightmare and Commandos 2. New ones are added monthly. To my knowledge, this is the first time an ISP offers this kind of service. Personally, I'm all for the idea. Could this be the future? Half-Life developer Valve Software seems to think so." This looks really cool, but I'm curious as to how well it will catch on. It feels about 5 years too early to me, but here's hoping it performs well.

Unknown Relic writes "While far from confirmed, it is reported that Microsoft is seriously looking into buying, or may have already bought, Vivendi's Games Division. For those who aren't aware, Vivendi owns several prominent gaming companies, including Valve and Blizzard! While no official announcements have been made, one is apparently expected soon. While this would doubtlessly be a great boon to Xbox's library, it could be a shock to other consoles as titles which were originally planned for a diverse release become Xbox exclusives."
