It's hard for me to nominate a favorite oldy. I for one definitely would say damn near all of my favorites are on the SNES. Terranigma is a recent classic for me (since it never got a U.S. release). Ogre Battle: March of the Black Queen even though I STILL haven't finished it. ShadowRun, my first exposure to cyber-punk RPGs (and arguably my last). Mega Man X, which held my attention longer than its sequels did. Demon's Crest, but that's just Mega Man X again. Cybernator, as well as the original version, Assault Suit Valken. Axelay, arguably one of the greatest shmups of all time (definitely the best of that generation). And last bu not least, Super Earth Defense Force, not a stand-out title but the weapon system was really fun.
