The Tiger Woods golf for Kinect was actually quite integral to getting me on my healthy journey...with a chronic bad back and severe weight issue, getting active at the beginning was going to be difficult. How to start getting fit when many of the activities to get me fit would aggravate my back? Of course losing weight in the kitchen was 1/2 the battle, but the kinect golf, playing 1 or 2 full rounds a day, loosened and strengthened my back just enough to kick start me. Now I'm walking 8km/day and rollerblading 15km/day.
My wife and I also play Dance Revolution on Kinect...that's a fun, goofy workout too.
