What characters, track locations, retro tracks, karts, items, etc do you want in Mario Kart 8? I want Fawful to be playable. Other RPG characters would be nice, but Fawful is my most-wanted. That's about it for me, what do you want to see? Here is my roster. It's unlikely, but would be so sweet to see. (I made it before any characters were confirmed, so that's why characters such as Toadette are absent)
