If you already have a wii system but want it to be more functional and fun, you probably need to buy some wii addons.
Things you can buy include specialty controllers, chargers, chords, skins, cleaning kits, fans, repair kits and wii covers. All of these you can find at this wii addon store.
If you are looking for a great addon controller, the wii fit balance board can’t be beat. It already is used in a lot of games such as wii fit and wii ski, but there are a bunch of new games being developed for this fun, new controller. This controller prevents joystick boredom and allows even young children and older non-gamers to quickly get in the action.
Another great wii specialty controller is the wii zapper. It allows you to play arcade style shooter games at home. It is great for war and hunting games and other games that involve a gun.
