Seems silly to buy an entire controller, let alone a set of controllers, that you can only use in one game. It quickly becomes the only game you want to play, and it's great for gatherings. Plus it makes even the most music illiterate person feel like a rockstar...much like those who can't dance usually throw down at DDR!

Hard to find one? Online suppliers charging more or making you buy a bundle of games to order one? There's a reason for this: it is awesome--even if all you own is Wii Sports (comes with it.)
