>>33817971>worst Mario KartIt had the best retro course selection, tightest kart controls and great item balance. The only downside 7 has is the lack of a single player VS mode and missions, something its predecessors (DS and Wii) had.
The worst would either be Super, solely because it's redundant with Super Circuit existing, or 8 for having even worse item and weight class balance than the other games.
