Wouldn't trade it for anything.

MX Unleashed is a motocross game from THQ and Rainbow Studios that far surpasses many. It's not necessarily perfect, but it's smart, well thought out, and very fun. You'll mainly be playing on a motorcycle, but you can compete in races to unlock a monster truck, a biplane, a helicopter, and my personal favorite, a dune buggy, to use in the games Freestyle mode. There's not much I have to say about this game, except that you should definitely check it out, whether you're a motorcross fan or not. I guarantee you'll absolutely love it. Do yourself a favor and, please, at least rent it.
