Zelda II The Adventure of Link. No, I'm not kidding
I love it's RPG aspects and the challenge it provides. Initially I even hated A Link to the Past because the game made such wimps out of many of the ennemies from it's predecessor, especially the Ironknucke Knights. I warmed up to it later on, bt it could never come close to the second one for me.
Zelda I is on the second spot, unless Hyrule Warriors counts
