The Nintendo Wii mainly relies on the use of wireless controllers, particularly the Wii Remote. The unique motion-sensitive design allows you to play games using gestures in addition to moving thumb sticks and pressing buttons. This approach makes gaming on the system more immersive and fun, but also forces you to rely on battery power. Using standard AA batteries can get expensive, so replacing them with rechargeable batteries is a wise idea. You may have to resync the Wii Remote controller if the battery charge wears off or after using the controller on a different Wii system. Writer Bio
