MS is getting big on cross platform playability. Lost Planet Colonies Edition, Shadowrun,
Universe at war, Alan Wake, Lost Planet 2, Final Fantasy fucken 90. Anyhow, there are a few out there but I think it'd be sick to play MW2 and Madden with 3X the amount of people. 360, PC and PS3 players all on the same server list, that'd be fucken sweeeeeet.
