Nintendo came to Denver today with a truck full of Mario Kart Wii.  After spending some time w/ the wheel and the game, I can sum it up with this:  "Mario Kart Wii is gimped, but still walking and a decent time".
There's a lot I could gripe about but my biggest complaint is racing against humans online or off is just so slooooow.  It really feels like gong through mud unless you hit a power arrow or take a shroom.
Its a pity The Big N didn't spend more time w/ it.  I'll still have fun w/ it I'm sure, but it could have been so much sweeter.
