And I believe everyone here owns a 360 also, including me, but you don't see me bashing games that don't legitimately look like shit miles away, while praising PS3 exclusives.
People are just threatened by Heavy Rain, and I feel confident saying that a game as sophisticated as Heavy Rain or even Uncharted 2 in it's cutscenes could never come to the 360, just because the PS3 is seen as more of a art house system, which more sophisticated players.
