Go on and hate on Sony or Microsoft who whoever the hell you want, but I never understand he idea that someone owning a PS3 would never touch third party games. If you only have a PS3, there are tons of great games to play. Granted that some of these games are inferior to the 360 versions (except Oblivion and Burnout Paradise), but if you only have the PS3, most third party games aren't poison.
Personally, I think all you console manufacturer boner strokers are crazy. Even if you somehow felt you needed to champion something to make yourself feel better when you play it, at least let it be the PC. Have some dignity for crying out loud.
