Well i bought the Xbox360 version and i like it so far. So far the AI is either easy and simple to beat. I have won the final stages of some story mode games with the guy simply flipping off the stage. Then you can have the extremely cheap as hell AI opponent that sometimes wont even let you get off the damn ground to move (Jedi apprentice) I haven't done any online battles yet but i look forward to doing so once i get my skill up. There is surprisingly NO RUMBLE SUPPORT on either PS3 or XBox360 version of the game.
I honesty i didn't really notice until someone brought it up on a thread on the IGN boards but is disappointing not having it optional. So if you are a fan of the series i think you will enjoy it and for other so-s fans i think its a worthy rental.
