The Final Fantasy series should have ended with FF7.
As long as this isn't a rehash of Super Mario 64, I'm interested.
I agree that it would have made for another top tier Nintendo franchise. We haven't seen a new "breakthrough" Nintendo franchise since Pokemon.
The Megaman series started to go downhill after they couldn't think of any interesting names for villains that ended with "man". Sure, Iceman, Flashman, Bombman and Magnetman all made sense, but the ones that come after...oh let's say Mega Man 3 were just terrible.
