Me and my friends are about as hard core as you can get about mario kart, and I have been fantasizing about making a mario kart clone type game on the pc. I made a little kart model to ease my pangs.
just under 3k tri's one 1024 for the body and a 512 for the wheels. Both could be sized down if needed without much loss visually since they are mostly gradients and flat colors. These are just viewport shots but I'm planning on a heavy dose of specularity or env mapping if it ever sees an engine.
My next goal is to add a rider with a bobblehead-sized helmet and then animate him turning left and right as well as a wipeout anim. If I get that far then I plan to tackle an entire course for this puppy to drive on.
