The worst that has happened is smashed fingers when a friend and I were playing against each other. Although, to be honest, I was probably beating him and that is his way of trying to throw me off. It smarted, but no permanent damage.
I make people wear the safety strap if they are going to play around me.
Also, with Kinect I have sent my glass of water flying across the roof a few times. Trying to jump to get something quickly, and f-l-i-n-g! Airborne water glass, splash, and I have something to clean up.
