personally, i'd trade it for killzone 2. i finished both games, through rental. ratchet was good, but i dont think i'll ever play it again. same with uncharted. killzone 2 is different in that they have multiplayer that will have replay value for quite a while.
Currently loving my Wii x2, Xbox 360 Pro & Xbox 360 Arcade, and Final Fantasy 7 Advent Children Limited "Cloud Black" 160GB PS3
