The Wiis central feature is the unique controls, they may make Wii Sports what it is but they go a little further if you try out some other types of games. If you have tried a Wii have you tried Zack and Wiki, it is really a pretty ideal implementationn of gesture controls. If your into shooters have you tried MOHH2 or RE4 Wii? Those both really show how archaic dual analog is for a 3D shooter. Though not included with the basic system the balance board and Shaun White are also an amazing and unique experience. The controls are really integral to the system, if your not about them then the only other big features are the nintendo titles. If your not interested in those either then really there is nothing for you on it.
