Steam is the world's largest digital game distribution platform, supporting all major operating systems, including Microsoft Windows, Mac OS X, and GNU/Linux or SteamOS, Valve's own distribution derived from the acclaimed Debian GNU/Linux OS.
[...] There are approximately 6,500 titles in the Steam library. Almost all of them are being supported on the Microsoft Windows platform, a little over 2,300 have support for the Mac OS X operating system, and 1,500 titles offer support for Valve's SteamOS and any other GNU/Linux distribution out there.
[...] Even more good news: [...] Many other games will have support for the Linux platform soon, mainly because Valve will finally release its Steam Machines gaming console / personal computer in November, which will be powered by the company's Debian-based SteamOS GNU/Linux operating system.

Sounds believable. I heard a story about emulation. Yeah I know this is Sony and I'm mixing the streams, but consoles like to sell oldgen stuff at the usual premium price, while otheros could run MESS. So how you you sell SuperMarioBrosRemake-2015 on the PS3 for the usual $50 if someone can just stick linux, MESS, and a snes rom of the original MarioBros for "free"? (Free in quotes in that the snes rom is technically illegal)
I played with my retro-pi for a couple weeks till I got sick of it. Probably dig it out and fool around some more later. Chopperlifter and the original mariobros and for some reason the earlier the arcade ripoff the better the gameplay so out comes missile command and pacman and asteroids. The "modern gaming experience" sucks compared to asteroids on Atari2600 (in an emulator), even if the modern stuff has higher resolution.
