Even if there are already more than 3,000 games on Steam that offer support for the Linux platform, Valve wants to let Linux Steam users access even more games, especially Windows games that never received Linux support and probably won’t, though the company hopes it’ll also encourage developers to port their titles to the Linux platform in the near future. Therefore, Valve is introducing today a new and much-improved Steam Play functionality, which includes Proton, a modified distribution of the Wine software that lets Linux and Mac users install and run Windows games and apps on their computers, to allow the installation of Windows games on Linux directly from the Linux Steam client.
