If anything else, if we only have 8 playable characters, that's fine, but I'd like to see more if at all possible. Would be fun to see if there can be more Rabbid Mario characters alongside with actual Mario characters.
Hell, what they could do is if they introduce more characters, if making new dialogue for the Mario characters is too much work, make characters like "Rabbid Wario" "Rabbid Waluigi" "Rabbid Daisy" "Rabbid Rosalina" and so forth.
Honestly, Just want to be blown away by this game since it definitely has done the best job out of any game to grab my attention when there was none to be had.
