And SF3! And parts of SF2!
The bigger the fighting game, or game in general, the more complaints will be aired.
That's such a weird thought process. Tons of FGC people cross pollinate. Tons of people play other fighting games. Tokido was a GG and KOF player, IIRC. Xiao is a KOF player. LI Joe loves like everything. A ton of the old heads play different games, and did so in the olden days. Some people just end up liking a particular type of game. Hell, people are playing Tekken as well as SF.
Capcom absolutely does not get a pass. They get dragged every day. People just enjoy the game enough to keep playing it. That's how it is for literally eveything. I have more fault with people claiming they are done with capcom and supporting other games but doing nothing to help their supposed title survive. They spend more time complaining about SFV and not promoting KOF, GG, or whatever. And the negativity doesn't look good for anyone.
Again, none of this is really rocket science. People enjoy SFV and the complaints are warranted but not really indicative of how everyone thinks. Things would be much better if people spent their energy elsewhere instead of focusing on things they don't like but whatever.
