Im surprised this thread doesn't exist. I would go with GBA. It has the most boring tracks and its all 2D!

GBA sorry thought this was worst track xD

Probably the GBA version. The cars were so loose; they never stayed on the track... Even on 50cc! I rarely play the GBA MK now.

actually I would have voted MKW if it didnt have online , but yea MKSC is pretty bad too

I don't have the GBA version, but I saw videos of it. It looked VERY crappy.
The music sucks bad too.

MKSC. The graphics were garbage and the tracks weren't great, but it did have one or two epic tracks like Ribbon Road and its Rainbow Road. xD
I do respect the fact that it is a game on the GBA.

The GBA version is definitely lacking graphics wise, but it is a small screen.

I never played GBA either, but it doesn't look like the best one >_<

GCN and GBA but you can't compare the consoles so I'll vote for GCN because it has been the only Mario kart that bored me out in 2 months.

I say SNES
