The Wii in Motion

The Nintendo Wii's wireless, wand-like device is used to direct on-screen action, yet the device is often slipping from gamers' hands during interactive games such as tennis and bowling, injuring persons, pets and furniture - and in one case, going through a $3,500 television.
Jim Walsh's blog WiiHaveAProblem is dedicated to sharing the Wii's "casualties," which he calls "the latest trend in gaming violence." According to Reuters, the site has received 3 million pageviews since it launched, and he receives 20-30 emails a day detailing woeful tales of over-enthusiastic players and Wii damage.

Not only are the controllers slipping out of hands, just the act of playing these new motion games is injuring gamers. The Wall Street Journal is calling inflamation suffered from swinging too hard "Wii Elbow."

And don't think it's because gamers are out of shape. According to MSNBC, Detroit Tigers lost star relief pitcher Joel Zumaya for three games due to an inflamed arm caused by playing "Guitar Hero" on the PS2, a game that simulates playing the guitar.
