Nintendo's Wii game console isn't just flying off store shelves -- it's flying out of players' hands. The game company's president announced Thursday that the company was investigating reports that players were losing control of the game's remote, causing it to crash into nearby television screens, ceiling fans, even windows and dishes. The system's weak point is, ironically, its unique selling point: a motion-sensitive controller that's waved like a wand as players participate in video swordfights, bowling, golf or tennis. But apparently, some gamers aren't wearing the controller's strap around their wrists or are wearing it too loosely. There are even some reports that the strap is prone to tearing without notice. Multiple reports have surfaced of out-of-control Wii accidents; the Web site Wii Have a Problem is keeping a running tally. Communicating with customers Nintendo President Satoru Iwata acknowledged Thursday that the company may indeed have a problem."Some people are getting a lot more excited than we'd expected," Iwata told the Mainichi Daily News in Japan. "We need to better communicate to people how to deal with Wii as a new form of entertainment." The company sent an e-mail to new owners this week reiterating the need to wear the strap properly. The company has not decided on any specific measures to change the strap, Nintendo spokesman Yasuhiro Minagawa said.
