3 has a different feel with its overchartedness but it's no more different than your SMB2s.
I think the real downfall for GH was jumping over into other instruments. I honestly think that if they hadn't tried to latch onto Rock Band's coattails and just stuck with being a guitar game that the rhythm genre would be a lot stronger right now for both franchises.

I tried to have a fierce rivalry with SuperNiceDog, but he made me look worse than a GameFAQs Contest!
if we're including games, i await to see the eventual NES Mario games being listed.
also Jak 3 was a ton better than 2. what in the hell. there... really aren't that many games i can think of that fit this. mainly because it's rare to get a trilogy within gaming. god of war might fit this i guess, if 3 wasn't as good as 2. no idea.
