The major problem is, the release of Halo 2 for Vista was strictly a ploy by Microsoft schemers to convince people to buy Vista. I think it was planned from the beginning to put as little time, money and effort into the port as possible. Doing anything more would negate the money made from tricking people into buying Vista in the first place. It's really sad to see Halo 2 used in this evil way. [Edited on 05.15.2010 10:32 PM PDT]
