But I also think that's why Smash has so much massive appeal because you have all these different characters from different world and aesthitics colliding compared to some regular fighting games that have most characters looking kind of similar.
Killer Instinct kind of has that same feel too though, While the characters had the same art style and vibe, But the cast is outrageous, I mean you have a Half mechanical Raptor, Skeleton Pirate, Sub Zero Alien, Killer Cyborg and Werewolf going at it which makes it the that much more awesome.
