I’ve never seen people quit or give up in a fighting game as much as SC6, and I’ve played MKX and Injustice 2! DOA may be pretty bad, but I’ve had a nicer time with this community
Usually the people who are active in the respective communities have a bit more of a "fighting spirit," so I don't think you;ll find a mass of rage-quitters on 8WR or FSD. It's the casuals that are the problem, and since I'm not really a part of the larger SC community, I can't exactly sync games to avoid them.
I just think that since the barrier of entry is so low in SC, everyone thinks they have a shot in this new “e-sports FGC” era. Everyone wants to be the next SonicFox and thinks it must be easy. But even 8WR is full of whiny people quick to completely judge everything and give up. And it’s not nearly as active as this forum.
