How do you feel about crossover characters in traditional fighting games?

Not big on DLC

I'm fine with them if they're good characters.

I'm fine with crossover characters if it gets us baller remixes like this.

Depends on the game, but I don't like it in "core" games that already have an established setting and all that. Mortal Kombat has intentionally gone the route of "hey remember this 80s/90s action star" and that's fine, but I didn't like seeing Akira in SFV. Not that I played SFV, because it sucked.

That being said, I'll always prioritize moveset over aesthetic: If the character is fun to play, I'd rather keep them. Rather have them reskinned, but still.
