Maybe there should be a Bowser Shell cup with retro Bowser castles.
Bowser Shell Cup
GCN Bowser's Castle
DS Bowser's Castle
Wii Bowser's Castle
3DS or N64 Bowser's Castle or GBA Bowser's Castle 4. I perfer the N64 version anyways in DLC, they can remake tracks more than once. 3DS version kinda sucked. I think some of us want BC4 so I think they should return BC4
It would also be cool to see a Rainbow cup with retro rainbow roads
GCN Rainbow Road
DS Rainbow Road
Wii Rainbow Road
3DS Rainbow Road
I bet most of you disagree but there should be a Mario cap cup with retro Mario circuits. I've heard Waluigi the master of Mario Kart on YouTube say that there's no competition between the best Mario circuits other then the 3DS version. I like Wii version the best.
