I might be the only one with this opinions.

I do not want any spinoff or crossover or even one-off characters in the next Mario kart game. I just don’t think they fit. It think it is beter to have characters who actually appeared more than one time in the franchise. (Except the characters that already appeared previously in other Mario kart games, like Link or Honey Queen. Those I don’t care about). Also I don’t really mind the babies. I understand why people don’t like the babies, but I don’t really mind them.
