The Nintendo Wii has become a strange source of physical exercise, with worldwide reports of gamers shedding pounds while sweating to Wii Sports. Seeing the extremely lucrative business that exercise can be, Nintendo decided to build upon previous success and make a Wii game sheerly built around exercise. The game, Wii Fit, requires a special controller. This controller, which has been redesigned for an American and European release, can hold 150KG and allows users to better interface with the system. Over one million copies of Wii Fit have been sold since it was released in Japan on December 1st. Expect to see this game in America by May 19, and in Europe by April 15.
