First off, I love the SNES. But the fact is, a "jump" doesn't make the games automatically better. I would completely agree with there being a "huge jump" between say, early NES titles and early SNES titles, but not quite so much with late NES to early SNES. (That would also negate it being a jump.) True, Nintendo used mode7 at launch, but besides that, the main advantages you got were twice the colors, a few more sprites onscreen, and a more versatile sound chip. Being on SNES didn't make the games control better or get more fun.
