Ocarina of Time.
Windwaker was good. But the lack of Hyrule and Epona etc, as well as the cel shaded graphics meant it just didnt
feel like a Zelda game.
As for Twilight Princess, my opinion is a little bit biased. I bought the Wii version, not the gamecube version. As a result, i played the game for a few hours then got right fucked off with having to wave my arms like a twat each time i wanted to stab an enemy, or just cut some grass

Ejected the game with some major arm ache, didnt play the game again lol
