I'm not so sure if I want to see Mario Kart branch out to all of Nintendo, but it's gonna really be hard to top Mario Kart 8. There's only so many minor Mario characters you can add. *Koff koff*Cat Peach*koff koff*, so extending it to all Nintendo would be a good way to refresh it.

Possible Courses: and maybe, just maybe...GREEN HILL ZONE??
 * Hyrule Dungeon
 * City Trial (Kirby)
 * Mute City/Big Blue
 * Distant Planet (Pikmin)
 * Lylat System

Possible Items:
 * Warp Star (transports you ahead very quickly)
 * Clawshot (lets you grab onto another kart and move them)
 * Timber (plants a giant tree in the course that grows over time)
