The fact that Valve plans to offer digital distribution service Steam on all existing platforms is not a surprise to anyone. Steam client is already on MacOS X, many of the games distributed offering cross-platform support for this operating system.
Next step is porting Ubuntu Linux Steam client, Valve engineers wanted, initially, to focus on one distribution of the popular open-source operating system. After the full functionality of Steam client will be ported to Ubuntu, Valve does not preclude extension of compliance and for other distributions of the operating system.
Of course that run of Steam on Linux would be useless unless there will be games dedicated to this operating system. The Valve come with good news in this chapter: Left 4 Dead 2 has been successfully ported to Ubuntu, the game now undergoing additional tweaking to run at optimal frame rates by OpenGL (Linux not supported DirectX). Once this adjustment is completed, the Valve will begin to port the rest of the company’s titles for this operating system.
Earlier this year, Valve succeeded in launching Steam client on mobile versions for Android and iOS, Gabe Newell’s company is preparing a new interface for its digital distribution service, specially designed for use on TVs and gamepads.
