Mario Power Tennis (Wii)

Wow, if you want a major workout for your ARM, this is definately one of the games for you. It's just a regular tennis game, but you are swinging the remote to get the ball to the other side. You get to choose your character, just like any other game, and I believe each character has their own stats, just like the older games. And if you want to run back and forth for a little more exercise, by all means, do it. It's actually a pretty good workout on a Mario game!
