It's Pocahontas / Dances with Wolves, but with really amazing special effects.

That's a good point. My wife instantly disliked Mario Kart (while watching the preview on Nintendo Channel on our Wii) because of the wheel. She hated the idea of yet another thing to find a place for. I don't think four Wiimotes, two nunchucks, a zapper, and a guitar are a problem at all. But if I came home adding a plastic drum kit to that collection, I don't think she'd let me in. (At least the balance board that's on preorder will slide under the couch.)
