Many games feature a warning related to possible photosensitive seizures as a result of playing a game.
Risk of injury has been reported when improperly using the Wii Remote. As players concentrate on a game, they often will forget to maintain possession of the remote causing it to slip from their hand and possibly damage property or injure another individual.
Nintendo recommends that players use the strap included with Wii Remotes to prevent this from occurring. In addition Nintendo has introduced a material that slips over the Wii Remote to provide a better grip and increase safety.
