Yeah, why are the EBs filled with dopes?
They've got a newbie in my local EB at the moment, must be about 12. Man, I want that job. Stupid EBs not giving me work!!!
And I have DD.
EDIT: Ok. I've just played through the first two cups on 50cc. Random comments below:
~ There are lots of things happening on screen - items everywhere, mario-related baddies trying to get you, opponents trying to get you, takes a while to adjust, even at the front of the field.
~ Flower Cup has the coolest obstacle I've seen - moving tables on a cruise ship

LMAO! And you can release a Chain Chomp somehow, because one flew by me after I passed it, chomping its way into a wall.
~ If bright and cheerful are not how you like your graphics, stay away.
~ You start out with three karts, and unlock more by winning golds in the championships. I want Wario's Pimp Mobile dammit!
~ Wario has the coolest special weapon - a bob-omb that diables you attacker for a short period if you get hit. Yoshi has a targeting egg that spits out various items on the track on impact. I played with Baby Mario as well but didn't find his unique item...
Overall, IGN was way off. I give it a 9.4, because I played way too much MK64 and the easy difficulties on DD are way too easy. I can't comment on multi because I have no friends at midnight for now.
