Bad idea:
Add Paper Mario and Dr Eggman as characters, make Mario flash to fire colors for any fire attack, and make a Mr L costume for Luigi.
Nintendo hates Waluigi so I won't say anything else about that.
i think that making smash bros for switch 2 just a port of smash ultimate is the right thing to do because it would just be ssbu with more dlc characters. what can they do for the next smash game? add custom moves back?
