I've played it on GC, Wii and 64 also
But I'd have to say I currently prefer Wii, due to it being easier for me to control with the wiimote.

I do love 64 though, but not the races so much as the battles.

I liked Being Bowser as he had purple balloons and you could ram someone's balloons off them right at the start.

the wii one is the worst one because 12 racers is too many
you end being buffeted by a constant shower of items

I haven't got the wii version yet, I should probably give it a go.
I spent most of my second year at uni playing it on the N64, and bought it for my girlfriend for her birthday a year or two ago.
I'm so thoughtful.
