While we're on the subject of better living through video games, Powergrid Fitness has also come up with a fitness-oriented controller. It's the Exer-Station, and it's compatible with the PlayStation, Xbox and GameCube. You push, pull and lean on the controller to control the game.
Best Buy will start carrying the Exer-Station in March. Until then, you can get information and testimonials at the Exer-Station site.
