This month we should all be more active while playing Wii Sports for the Wii.

Wii Sports is a collection of simplified sports games that employs the Wii controller to mimic a real-life action such as swinging a tennis racket or pitching a baseball. The point of the game is mainly to demonstrate how the new control system can work for a variety of different games and get new users used to the controls using simplified mini-games.
