No one expects people to upgrade their OPsystem just to play halo2 :D woody998

that's true, but they'll lose a lot of buyers because it only runs on vista

do u guys have worse performance of backw compatible games as well?

its such a bad move making halo2 for pc only run on vista

i dont think everyone owning a pc will want to upgrade and give about 150 bucks for a new OS just to play halo 2

windows xp will still last for years, way to go bungie :s:s:s:s:s
