Well, I don't know if Linux is the future of gaming, but it seems to me that this guy, Gable Newell of Valve, is on to something. He is building up expectations, by releasing new information gradually, creating some sort of hype, but still making it believable. http://store.steampowered.com/livingroom/ Comments over the web seem to share some of the enthousiasm : http://www.osnews.com/story/27340/Valve_announces_Linux-based_SteamOS_major_devs_on_board http://www.linuxinsider.com/story/Valve-Beta-Boosts-Linux-Gaming-Full-Steam-Ahead-79043.html The idea of SteamOS is to create a Linux-based distribution, stripped down and optimized for gaming. http://store.steampowered.com/livingroom/SteamOS/ Indead, for gaming (or simulation), there is no need for a general-purpose desktop OS with lots of overhead. The Steam Machines will have this SteamOS pre-installed.http://store.steampowered.com/livingroom/SteamMachines/ He promises to keep the hardware and software completely open, as opposed to the gaming consoles that we have now. Mind you, he still wants the vendor-lock-in for the games from his store, but gamers will have the possibility to buy the hardware from different vendors with SteamOS pre-installed or not, or assemble their own using standard components. . Now suppose (I am wildly speculating here) that the Steam platform gets widely adopted and becomes an accepted standard. Either a Steam Machine, or any PC with SteamOS, or in fact any Linux distro that adheres to this standard. In that case, the suppliers of our favorite simulator and add-ons could release their product for Windows, Mac or ... "Any Steam-compatible platform" ... The way X-Plane is written, it doesn't need a full-blown desktop OS. Being cross-platform, they didn't try to adhere to one desktop environment or another. So, a stripped-down OS, optimized for gaming (anti-flaming disclaimer: X-Plane is not a game) will do. I am not saying that they should distribute it via the Steam store, just the fact that the platform is standardized would reduce the support hassle of different Linux distros. I can dream, can't I? Hey, Nvidia is dreaming too (but for a different reason, they want to open a new market for their graphics chips) : http://www.tomshardware.com/news/steam-box-steamos-nvidia-valve,24405.html http://www.osnews.com/story/27347/Valve_announces_Steam_Machines_
