Microsoft plans to use Halo 2 to sell Vista's new graphics capabilities when it's launched in time for Christmas. The Vista version will include the single-player campaign, the multiplayer version, the extra maps from the Halo 2 Multiplayer Map Pack, and the facility to create your own multiplayer levels. Halo 2 took a record $125 million on its first day of sale on the Xbox.
Making it Vista-only will limit sales to people who buy new machines or are willing to shell out for Vista upgrades -- which may not matter much, since Halo wasn't exactly a hit on the PC. However, Halo 2 should provide a good illustration of Vista's graphics potential, and this may impress people who don't actually want to buy the game.
