Hey guys. This is my first or second post I think so I'm sort of new to the forums. Anyways, me and my friend wanted to get Halo 2 for the PC so that we can play it after we hit the credit limit on Reach. I read that to play Halo 2, you need Vista. Because Windows 7 came out after Vista (I think?) will Halo 2 be able to work on Windows 7? Thanks.
