Nintendo has said that playing games on the Wii is perfectly safe providing you don't "overdo it", GamesIndustry.biz reports.
Safety tips were offered by US spokesperson Anka Dolecki in response to an article on ABC2 News, which looked at complaints claiming excessive Wii play was causing conditions such as tendonitis.
"Nintendo is committed to ensuring not only a fun gameplay experience on the Wii, but a safe one as well. Nintendo has gone to great lengths to inform consumers about the innovative and unique game-play experience on the Wii," said Dolecki.
She went on to talk about the Wii Remote Jacket that the company released some time after launch in response to "reports of minor incidents during overly enthusiastic gameplay".
"The Wii Remote is perfectly safe when used as instructed: use a firm grip, don't let go, use the wrist strap and make sure the game-play area has ample open space," added Dolecki.
"As when beginning any new physical activity, it's best to pace yourself and not overdo it. Some games, including Wii Sports, include in-game reminders for players to take a break every now and then."
The Wii is expected to finish 2008 with the highest installed base of any of the next generation consoles, outselling both its more expensive and high-tech rivals, the Xbox 360 and PlayStation 3.
