I picked it up, an extra controller, and have two wheels for it. It definitely takes some getting used to, and I wish the steering was a bit more sensitive (though maybe there is a setting for this,) but it's TONz0rZ-o-FuN. Just need to unlock some damned tracks. It does the DS thing where it has new tracks, and some old ones from various systems. Drifting is fun with the wheels, because you do it ROUGHLY the way you'd do it in a car. You start your slide by turning in, then you turn out, then back in again should you want to tighten it up at the end. It's easy to get the mini-turbos this way.
I've only played the first few circuits in single player. Multiplayer is fun, but split-screen is annoying as usual. (even on a fairly large TV)
Definitely a good game though, and it's nice that it doesn't cost any more than any other first run game even with the extra chunk of plastic.
The graphics and sounds are good. I'd rate them slightly above the GC version, but similar. It never really was a game that needed much graphical power.
One cool thing is that it uses your Miis all over the place. There is a level where there are several cars moving back and forth as obstacles. They are being driven by various Miis. I got backed over by SpiderMonkery once.
They also use them on posters, and other things like this. Anyway...
