As casual fun as Smash is this is objectively true, it's a franchise coasting on Mario, Pokemon, Zelda and being the only actual crossover Nintendo's truly had. You couldn't make a Smash clone feel as good to play as Smash because you're missing Mario. If you really wanted a Smash clone that people would be interested in it has to be an IP crossover pukefest with more substance beyond "just the gameplay" because fighting games are dime a dozen to fight each other for attention. If you're doing OCs that's twice the work, regardless of if you're doing a Smash-like or a Streets-like
