IGN has an interview with Drew Johnston, one of the developers of Games for Windows Live. They also have some pictures of the interface itself.
Over the past year, they have been hard at work ensuring the translation to the Windows Vista platform from Xbox results in an experience that is familiar and new all at once. As we near the release of Halo 2 for Windows Vista (May 8, 2007!!!), the first LIVE-enabled game, we thought it would be a good idea to let the LIVE guys lay out the skinny on the expansion of their service to Windows Vista. We spoke with Drew Johnston, Group Program Manager for the Games for Windows – LIVE team to ask questions that we have heard from many of you out there.
