Because the Wii Remote and Nunchuk controllers are only relatively dependent on each other, players are free to hold them in whichever hand is most comfortable. Perfectly suitable for either right or left-hand use, the Wii Nunchuk controller grants accessibility not often seen in previous game controllers. Also, the Nunchuk controller doesn't need its own power--it plugs into the Wii Remote controller when it's in use. So there's no need to worry about charging or replacing expensive batteries.
