I have to agree with Michael and Noxious. Play that game now! Familiarise yourself with it again so once it comes out on PS3, you can play it again and you'll have the necessary knowledge to make getting the trophies/achievements a walk in the park! xD

If that's what you're aiming for on the PS3 version of the game i mean. Regardless, it's a game that can be played over and over so do it!
