The BEST exercise game I ever found was Kinetic (not to be confused with Kinect) for the PS2 (that is PlayStation 2) and the old Eye Toy camera. The game comes with a special wide-angle lens so it can see from floor to ceiling, and wall to wall. I lost about 10 to 15 lbs. playing that game and watching my diet. "Kinetic" actually let you configure your exercises, or put together a reasonable set of exercises. It was designed by numerous exercise and fitness groups, and was very professionally developed.
The camera worked well enough to play it (if you were consistent and reasonably patient). There were punching and kicking exercises in which you kicked targets that would explode when you hit them. There were dodging exercises where you would dodge falling objects and kick or hit others. The game would judge your push ups and situps reasonably well, and it had a great cool down mode. I have considered buying a used PS2 and forking out the cash for a "new" Kinetic game because No One makes a game like this one anymore. Considering the fancy technology that is available, I'm surprised both PS3 and XBox360 have dropped the ball (pun intended) on this one.
