This game is not easy to use and just not that interesting. Like another reviewer said you can make the controls work and build your fighter up....but it isn't interesting enough to make it worth it. I wouldn't suggest even a rent unless you are desperate.
1) You do have to perform physical action (so excercise is involved).
1) The controls are not well designed. The biggest problem I have is that you must move your boxer with one hand (hence, you only have one hand to fight with much of the time). The second stupid design decision is that you can't move your feet around (gets things out of calibration).
2) The game just isn't much fun
