Sorry, but I'm calling bullshit
on this one. The parents aren't right. Nintendo isn't responsible. It's a GAME.
Say it with me... IT'S A GAME.
One more time, in case it didn't sink in: IT'S A GAME.
It might be a great idea, it might even help kids get in better shape, but at the end of the day, it's just A GAME, produced by a company that MAKES GAMES. If you want serious health and fitness evaluation software, don't buy it from the people who brought you SUPER MARIO.
Duh people... take some responsibility for your children and stop relying on society to teach them not to lick the light sockets.
Your kid probably was fat anyway.
