Just in from the Games Convention Microsoft press conference - Vista will have "more games in more genres than any other game platform out there," Rich Wickham (Games for Windows) claims. Flight Sim X, Halo 2, Age of Empires 3 expansion, Zoo Tycoon 2 expansion, Lego Star Wars II, Broken Sword, Lord of the Rings: Shadow of Angmar, Lord of the Rings Online, Rail Simulator, Alan Wake, Hellgate, Shadowrun, Crysis, Age of Conan, will be available on Vista.
That's a fair amount of games announced for the new Microsoft OS, Windows Vista, scheduled for release in early 2007. A reasonable amount of these games will be available before Vista's launch, and therefore won't just be Vista only games.
