From the press release entitled Microsoft Unites Xbox and PC Gamers With Debut of Games for Windows — LIVE we learn
REDMOND, Wash. — March 14, 2007 — Microsoft Corp. today announced the extension of the Xbox LIVE® games and entertainment network to the Windows®
platform, bringing together the most popular online console game
service with the most popular games platform in the world. Debuting on
May 8, 2007, with the launch of the Windows Vista™ version of the Xbox® blockbuster “Halo®
2,” Games for Windows — LIVE will connect Windows gamers to over six
million gamers already in the Xbox LIVE community. Then, launching in
June, “Shadowrun™” will for the first time connect Windows gamers with
Xbox 360™ players in cross-platform matches using a single service. “UNO®,” releasing later in 2007, will also support cross-platform play between Windows and Xbox 360.
This is pretty cool and I saw some of the demos when I was at CES in January. The funny thing is that one of my coworkers told me that we were announcing this soon but I thought he said "Games for Windows Live" so I thought he meant we were rebranding MSN Games. I didn't realize it was actually "Games for Windows — LIVE". This might get a tad confusing.
