SSB is probably my favorite fighting game. I don't get super into it but I was decent. Not sure what kind of level cap there is since it's more of a casual fighting game though.
Well, to quote from someone who's better then me:
"Super Smash Bros n64 was a party game that could also be played as a competitive fighter.
Super Smash Bros Melee was a party game that was better as a competitive fighter.
Brawl is awful as both a party game and a fighter."
But yeah, Smash Bros has a very high skill ceiling. The way high level players move is simply amazing.
After all, it IS going to Evo this year. Aka the biggest international tournament in the world, held at Vegas.
Wait for the match clips lol (1 minute in).
