"Phoronix reader Casper Gielen wrote in with some interesting information that may have been overlooked by other Phoronix readers. Casper wrote, "While browsing the 100 newest releases on Steam I noticed that 20 supported Linux. That's quite a lot. Of the 18 games under "coming soon" 6 support Linux. That's even better, which suggests that it's not just a lucky day but a real trend. Only 13 of the best selling games support Linux, but even that is a rather nice number."
So right now 20% of the new releases support Linux, 33% of the current "coming soon" titles support Linux, and 13% of the "best selling" games advertise Linux support. Those wanting to check out the games for yourself can visit store.steampowered.com and click on the various tabs.
These numbers are only likely to rise given Valve continuing to push more game developers to support Linux, SteamOS and Steam Machines will drive game developers and gamers to the Linux-based operating system, and Valve continues to work on new initiatives to help developers in moving their games to Linux — e.g. continued Source Engine optimizations, LLDB improvements, joint work on a new Linux debugger for game developers, etc.
