Wii Fit Muscles Past Grand Theft Auto

Wii Play America's Best-Selling Title Of The Decade...

Move over Halo and Grand Theft Auto because there may just be a new sales leader in town. It doesn't star a heroic, gun-wielding soldier and it doesn't allow you to run over prostitutes with your virtual car. In fact, by the average definition, it doesn't even qualify as a videogame. But according to data from the NPD Group, which monitors monthly and yearly North American software sales, Nintendo's exercise program, Wii Fit, is on the verge of becoming the second-best-selling 'videogame' in a decade.
