Games will be developed to run natively on Linux and SteamOS. Linux compatibility is already a feature offered through the Steamworks application programming interface (API), and according to Paradox Interactive, all of their recent games that have been designed to work with Steam under Linux will also run under SteamOS without additional modifications. Valve will not make games that are exclusive to SteamOS or Steam Machines, and has cautioned third-party developers against making games exclusive to the platform. However, Valve will not stop developers from making SteamOS-exclusive games, particularly those that are best suited for playing from the living room. Players will also be able to stream games from regular PCs running Steam to Steam Machines, allowing access to games that are only available for Windows or OS X. Through SteamPlay, users can play games available on SteamOS that they already own on Windows or OS X and will not need to repurchase the title.
