How would any of you feel about non-video game origin characters anyway?
Part of me feels like I’d be fine with it as long as they’re a character that has had plenty of notable games, but at the same time, there’s still other “true” video game characters they could be adding instead.
It’s like YouTube promoting celebrities over people that actually started on YouTube.
That's an incredibly apt and timely analogy, really. Huh.
Personally I'm of the opinion that adding non-game characters would kinda make Smash lose its focus, as even when other fighting games have guests, they very rarely break the game's "rules" entirely. To me, Smash's focus is video games, and there's still a lot of untapped material there.
That being said, certain non-game characters would still manage to get me hyped. Mickey Mouse is my go-to example (bonus points if he has the magic blast from the end of Fantasmic as his Final Smash), even if he's impossible.
