I'm greatly enjoying Extraction on PS3, though not as much as on Wii, largely due to the fact that it's more awkward to turn the Move controller on its side (go figure, but it's true). The game certainly looks...good. It basically looks exactly like the Wii game (seriously) with smoother character models, but not...as smooth as you'd like. I mean, the game is a STRAIGHT port.
Dead Space 2, though. I mean...damn. What a game.
