man you guys are babies,zelda 2 was hard but certainly nothing impossible
aside that the award goes to the original legend of zelda for the really dick choices that they made
The Legend of Zelda is the hardest. I'm pretty sure most of us have come to that conclusion by now.
But not counting that one, I'll probably say Ocarina of Time, just because the other games are much easier. And I'm not counting the "bad" ones either. (Like PH…)
This may sound stupid, but personally, the hardest I've played is Phantom Hourglass. It's not like the puzzles are hard, but controlling for me was really hard - not sure if that's the case for other people.
Its OoA, i still havent completed that game. Im still trying to complete juba jubas belly, OoA has got to be the hardest Zelda game i have played since the NES, and im loving every minute of it
For the 2D games, I'll say the first one is because it's not too puzzle heavy until the last dungeon and link controls like a tank. The hardest 3D zelda game is Majora's Mask because that is very puzzle heavy and you can only get four heart containers, so they make you do side-quests to get heart peices. And I love it for that!
