I'm not. That just means that some people are competitive in it. It is by no means the most popular fighting game. By any metric besides there are a very small minority of people, the FGC who care to be competitive in it. And that doesn't really mean much.
So again, on what planet? because on earth, both casual and competitive audience is playing other games, and shitting on sfv.
I don't hate street fighter, i'm literally playing it right now. But i'm not going to ignore the situation that exists. And i'm not going to pretend a very nieche competitive community as proven by SFV's sales means anything to the potential broader demo for fighting games.
