I didn't have a good time with Zelda II as a child. However, I was ignorant of RPG mechanics and I believe I didn't understand how to properly play the game. I've revisited it in the past year or so (and at this point I understand the genre a lot better and I'm tolerant of grinding) and I like it but its old-school difficulty makes it a tough slog. I like that the creators did something different and alternate approaches like Zelda II should happen every know and then but not too much.
