Nintendo's latest game wants you off the couch

With its exercise components, weight and body mass index tracking (as well as gentle nudging when you don't exercise for a few days) Wii Fit can certainly sound more like a health gadget than a game. In Miyamoto's eyes, however, it's a video game.

"In my mind anything that lets you interact on a TV screen, technically speaking, is a video game," he said. "But it's true that with Wii Fit you are doing things that you typically don't do, like checking your weight."
