Graphics are Superior in this Genre of games. Playability is wonderful, but the game itself should be longer.
This is a definite family must have if you are able to get the 360 at opening of the system. (Also one of the only family friendly titles). It is easy to learn, and should take the average person just a few minutes to learn and use the controls. Although they should have put the training level as the first level, instead of throwing you in so you know what you are doing when the tutorial comes on and makes the tutorial not as useful.
The value of this game is great for a family, because it can be played by Kids and Adults alike. And Co-Op, although looks like it was meant for just one player, makes it even funner competing for combo's/K.O.'s. The challenges, hidden secrets, give it a descent replay value as well. Its a descent story line, and I would like to see Kameo again, in a larger game.
