I haven't used the Zumba game, but Active 2 is great. Very few problems with motion detection, the exercises are varied quite a bit, and you can select from easy, med, or hard epending on your fitness level. There's also the ability to make your own custom workouts as opposed to using the premade workouts or programs. My wife and I are both using it and it's definitely helpful (especially since we've been having problems getting to the gym lately!).
