The games I remember loving most are:
Zelda
Mike Tyson's Punch Out (I could beat it without losing a match, and TKO Tyson in the second round)
Blaster Master
Bionic Commando
Metroid
Tecmo Bowl
Castlevania II
Guardian Legend
Super Mario 1,2,3
Mega Man II (and the others, but that one is a pinnacle)
RC Pro-AM
And many many others that don't come to mind right now. Actually, and this could be a bad memory, but I seem to remember Addams Family: Fester's Quest being quite good.
