Here me out: Paper Mario Kart

The roster would be insane, that's a given. But I think they could do a lot of cool stuff with the kart designs. Some made of origami, others made of cardboard, stuff like that.

The tracks could be based on places from the games, but some new unique ideas would be nice as well.

I just thought of this while typing, but what if they had a sort of story-mode? It'd be fitting given the games are, y'know, jrpgs. (most of the time) No idea what a kart game with a story would look like, but Nintendo can cook when they try.

Back to the roster, I think the partners from all the games are a given.
Villains like the X-naut characters, Bowser, Kammy, Rawk, Tubba, Shadow Queen? And various enemies like Magikoopa, Goomba (they can drive, right?) THE KOOPA BROS. And notable NPCs

Just a thought I had, and wanted to share it somewhere. I hope a talented artist gets the same idea one day and draws concepts for the potential of this sort of game. Or better yet, Nintendo just MAKES the game.

Edit: I'm in my mid-20s and I'm writing a novel, how tf do I make an epic typo like "here me out." 🥴
