Basically, Nuki’s problems with SF4 are the same as most people’s. He hates crouch techs, FADC Shoryus, how ridiculous SRK shortcuts have become, stuff like that. He finds SF4 Chun boring to play, and can’t accept certain things like why after something like cr.LKx2 tick throw, absolute guard doesn’t come into play from her crossup kick into cr.LKx2 followup.
He’d much rather see a new Darkstalkers game, CvS or even SF5(but feels that parrying feels the most complete in 3S so bringing that back would be unnecessary). He doesn’t care much about balance, considering he loves fighting CvS2 Sagat, but he’s more concerned about whether or not mindgames and reads come into play. This could explain why he plays 3S and VF so much.
