There is so much unused stuff within OOT and MM that you could make a third. There's also a fan-made expansion that actually uses the 64DD, like Ura Zelda.
I was thinking about that earlier. How many would say the same about the newer titles, even those for which that particular one was their formative years Zelda.
I disagree - I used to play this game 8 hours a day as a kid and at this point every part of the game brings me pain. I played MM slightly less and can still replay that game. Master Quest was dope I may give it another whirl one day. I have only beaten MQ once.
