Wii Remote

With the Wii Remote, Nintendo opens up gaming to people of all ages and abilities. The Wii Remote mixes the familiarity of a remote control with the latest motion-sensing technology. Game designers love finding new uses for the Wii Remote. In a tennis game, it becomes a racket you swing with your arm. In a driving game, it becomes a steering wheel. The possibilities are endless! The Wii Remote also packs a speaker, rumble feature, and external extension connector for other input devices, like the Classic Controller.
