Golden axe.
To me its easily Zelda Ocarina of Time. to me that whole end game sequence from the moment you walk in the room to the last battle with Ganon is unmatched.
it might be because the whole game built up to it. wasn't some hidden boss they pulled outta their asses or nothing. he was Ganondorf and he was there from beginning to end and when you fought him in the end it meant more because of it.
just imagine if Zelda games were a lil more cinematic.
