Apparently seeking to stem the possibilities of death by gaming, the Chinese government is mandating that hard time limits be imposed on online activity, setting a firm restriction of three to five hours of consecutive play, and a required reak period of at least 5 hours before the gamer can resume:
The new system will impose penalties on players who spend more than three hours playing a game by reducing the abilities of their characters.
Gamers who spend more than five hours will have the abilities of their in-game character severely limited.
Depending on how you look at it, this kind of regulation makes sense. Of course in most western countries, ruining one’s life through obsessive game play is recognized as a person’s God-given right, so we probably won’t see something like this ever in the ‘States.
