Ocarina of Time had additional dungeons/magic at one point
“Yes, you may be absolutely right, although I can not remember exactly all the details. There really is a difference between the temples, which we wanted to integrate and those that exist in the final game. And that had something to do with magic. We thought of integrating some actions, some plot threads, and some puzzles that have something to do with magic abilities. We have come to the conclusion that other, already existing, just regular items to be a worthy replacement. So we had originally three temples, which would capture the young Link, three temples for the adult Link and three in which he was to learn each spell – but instead we have eliminated a temple of it. In the final game is now so 3 plus 3 plus 2, or 8 temples to find.” – Eiji Aonuma
Because this information comes from a machine translation, not all of Aonuma’s words are entirely clear. However, he seems to be saying that initially, there were plans to include additional dungeons/magic in Ocarina of Time. In the end, though, some of those ideas were scrapped.
