I bought my daughter Madagascar Kartz for a Nintendo Wii for her birthday and now I realize that I might need to get a wheel. Does it work with and without a wheel or what? I have no clue about Wii's but my kids love it, it's definitely the next generation recreation. Thank you.

You do not need to purchase the wheel, it's just a plastic piece the controller snaps into. It's just used to make you feel more a part of the game. I wouldn't waste money on it if I were you. You may want to get the motion plus attachements for the controllers though.

Here's a link to nintendo that will explain what the controllers and accessories are for Accessories at Nintendo :: Wii :: What Is Wii?

You're very welcome. Stick to the nintendo site for information about the Wii items, it's a nintendo product so all their information should be correct.
