Valve’s Linux support for Steam rolls inexorably closer, and now Linux site OMG! Ubuntu have spotted that several games have begun to list Linux system requirements.
PC Gamer notes that the Linux requirements seem to only be visible on Linux operating systems, and screenshots taken for games like Amnesia: The Dark Descent list components like Ubuntu 12.04 LTS, Mint 13 LTS, or Fedora 16, fully updated, as their OS. TechGage has screenshots showing the requirements for games like Serious Sam BFE.
It’s also widely speculated that the Steam Box living-room-console-PC, whose existence was yesterday confirmed by Gabe Newell, will use Linux as its backbone.
