When the Nintendo Wii was first released, several people took Wii Sports too seriously. The wrist straps to the controllers snapped, and Wiimotes went flying into a plethora of very fragile things. When Nintendo replaced the straps with much stronger ones, it seems that some people went crazy. Now, several reports are coming in that Wii gamers are facing a new problem: tendinitis, due to moving too much. Since gamers get much more physically into the game than they normally would, they try to mimic the actual movement the activity on screen would require. This stresses muscles a lot more than you'd think, especially after a long period of time. Most problems are surfacing in 30-40 year olds, who really don't play too many video games, and suddenly became very involved in Wii gaming. Strangely, it's actually children that warn adults not to get too into gaming.
