I think having tons of ways to keep the experience from getting stale is going to be a theme for pretty much everything posted in this thread.

With that said, I still find myself replaying Secret of Mana again a hell of a lot, despite 100%ing it a good long while ago. The combat system - in particular, the collision detection - is incredibly tight; and the aesthetics are some of the best the SNES had to offer, with a wonderful color palette and Kikuta's brilliant soundtrack. Cozy as fug.
