This game is a beast. It's so jam pack full of features that it makes lesser PCs cry. Even on nicely spec'ed systems I've noticed additional latency in joystick response compared to older versions of SMC. Not a ton, but even a few ms difference can be felt to a veteran player. The new features are just too wonderful to do without though. I think if I had to give something up it'd be the themes and skins. Would this reduce the size of the game enough to give a performance increase? Maybe a NES only version with just 8-bit music and graphics?
