This game has REALLY good reviews and is 40% off so I thought I would mention it.
Kinect Sports is on sale on Amazon right now for $29.99 plus FREE shipping.
It has different sporting events- track and field, bowling, boxing, soccer etc and has numerous multi-player games.
As always this is Amazon so the price could change at any moment.
