I would watch this video below first and decide if it's worth the purchase price right now. Seems really platformy, and too scripted. To me this is a much better game to watch someone else play than spend the $59.99 just to play myself. Looks pretty much on rails the whole ride through, which was one of the things that annoyed me about Force Unleashed.
