How 'bout Kid Icarus and Kung Fu for the NES (ooh, and the Dragon Warrior series too... I played the first two, then waited and waited and WAITED for 3 to come out. Finally it came out, but it was too late for me to be interested in it anymore).
And some Square love on the SNES (I'm counting on this, actually – just sold my SNES with FF2, FF3, Secret of Mana, Secret of Evermore, etc.). I think I only rented Chrono Trigger once, so I'd happily pay to really dig into it and see what the fuss is all about.
Square(-Enix), are you listening?!
EDIT: Forgot Battletoads! though it may be complicated with Rare and all...
