I know it's stupid to put this much thought and weight into a fake concept who's entire purpose is to be "100% impossible except maybe in Heaven" in the first place, but what I love about that OmniVersus concept we've built up is just how divorced it is from the never-ending fandom discourse you'd find in places like the Smash fandom and other related fandoms.
No more constant back and fourths over what characters, stages, mechanics, whatever "deserve" to be put in, what "makes sense", etc. Just a place where you can do whatever the f*** you want. Let your hot takes become your own personalized reality. The only arguments I'd want to see come out of this, in the impossible scenario where such a game is tangible and real, are playground "nuh uh, my custom character is stronger than yours!!!" type crap. Nothing more, nothing less.
