I personally have some issues with this. While they have tried with the game, why insist on Vista? An unprincipled attempt at boosting sales of Vista, it will probably just hurt sales of Halo 2 though. And why the delay between the xbox version and the pc version? The graphics are impressive though, and given how much I liked the original, I may suck it up and load Vista onto my machine for this one, will need to think about that for a bit first though
