Judging from the review, it sounds kinda like dissidia; build up a set of points, and use them to deliver a killing blow.
EDIT: I've bought the game and played it for a while. I think it's pretty okay, though I don't how much replay value I'll get out of it once I level up all the characters I play with. So far my favorite character is Sly Cooper.
Have anyone else bought it yet? If so, what do you think of it, and who do you play?
