I don't know what peoples problem with this one is, it's not a best seller, but as far as Kinnect games go.. it's a winner!
Seriously will make you sweat, play it for a few hours and you will definitely be feeling it the next day. Graphics are excellent and if you have your Kinnect setup properly is quite responsive and intuitive.
The game is fun to play for about 10 minutes...once you get into the countering and advanced level moves, the kinect decides not to pick up all of the movements made. Punching kicking all registers, but counters and combos are hard to do. Otherwise, a cool game worth a rent.
