Legend of zelda is not what you think it is in its prototyping stage! The original legend of zelda had many builds, the most interesting is the oldest! It was supposed to be just dungeons, have a dungeon select screen on a first person view which is not in the final released! Iwata once admit this on Iwata ask, he also said that they changed it because of miyamoto! There is a screenshot of it on a book exclusively released in japan called Hyrule encyclopedia! Iwata also released some concept arts!
