But then that would cut out most of the mario characters people use. I would prefer adding five characters from the original smash bros as guest characters, Samus, Fox, Ness, and Falcon, and Kirby. (Maybe axe ness for the sake of having an even number.)
do we really need metal mario, gold mario, pink gold peach, baby peach, baby mario,baby daisy, baby rosalina,etc?
whats next baby toad,baby toadette, metal toad, shiny platinium toadette?
they even cutted diddy kong and funky kong which were actualy a disersity choise for more mario costumes basicaly, heck no idea why dk,diddy and dixie kong arent always in mario kart instead of adding more mario characters alone.
seriously they just have no idea what to add and keep adding several characters that are all the same, they could use some more variety and im not saying to add all smash characters but like one from each franchise.
fox
samus
captain falcon
olimar
pikachu(or pokemon trainer)
kirby
pit and so on.
one from each series with more emphasis on mario characters and stages from all Nintendo games.
