Halo 2 won't be "The" VISTA title because it is an old game that is mediocre at best. It doesn't live up to PC FPS standards because the original one didn't either. Microsoft should have given it away with VISTA ultimate to try and boost sales for both. Why on earth would someone pay full game title money for a game this old? This game may be the best FPS on the xbox but it is a far cry (pun intended) from being a good shooter on the PC. It is average at the very very best.
