To be honest, I always viewed Final Fight 2 & 3 as inferior to the original because they never graced the arcade before coming to the home console like the original. They were direct-to-video, man; this lowered my view of them back in the time when arcades were king.
With this said, I never played either sequel as a kid back in the day, and I was sore at Capcom for making Final Fight a one player affair on the SNES, so I didn't want to give them another chance with their sequels.
