I noticed the question posted below and wanted to say that I own both versions (don't ask) and have found no significant differences between them. As a result, I'd suggest buying whatever version you find cheaper.
If you only own one system, you're not missing anything by playing it there, and the store-specific pre-order DLC items are nothing to write home about. --- I used to think Resident Evil 4 will be a bad game, until I hear its also on PS2 - Antipikachu
I own the 360 version and really love platformers, had a blast playing thru this!. --- Currently Playiing: Max Payne 3 (360), Batman: AC (PS3), LoZ: SS (Wii) Diehard Buffalo Bills & Sabres Fan!!...XBL GamerTag & PSN: buffalo29
