Yes, Dance Dance Revolution. Don't worry I can't dance either nor do I want anything to do with that game. It is a fun party game for adults and kids though. It comes with a pad that is in the same format as the arcade version. You have to use the controller and nunchuck as well for the arm motions.
If you go into the wii shopping channel there are a ton of games you can download for wii points (100 points = 1 dollar). Most of the older games are about 500-800 points and save on the machine. You have to have the wii hooked up to the internet to get them though. They probably have a couple hundred titles available old versions of SuperMario Brothers, Sonic you name it.
