Microsoft has officially begun its unified Games for Windows program at stores today with the release of two titles, Traveller’s Tales’ LEGO Star Wars II: The Original Trilogy, and Relic Entertainment’s Company of Heroes.
All games participating in Games for Windows will feature a distinctive branding bar similar to those used on console game boxes. Games for Windows titles are required to meet a number of criteria, including: widescreen support, various 
reliability standards, 64-bit Windows support, Xbox 360 controller support for games with gamepad control options, streamlined game installation, the ability to be launched from within Windows Media Center, as well as Windows Vista-specific features such as compatibility with the upcoming operating system’s integrated Games Explorer.
