Played 3 at a friend's house and loved it, spent an entire weekend their beating the game =P It is quite a bit of fun to use the motion controlls..a helluva a lot more fun than the normal button mashing imo. I don't like most normal fighters so for my money the only way to play a fighting game is with motion controls.
Definitely a great pickup for anyone who likes DBZ and fighting games...I especially love how they did the transformations and allowing you to skip tiers and go straight to high level transformations.
