It could just be me, but this "entirely new" vision of Zelda seems to be a remastering of Zelda II. Last I heard, there was a lack of "dungeons," but there are shrines and such. This is similar to how Zelda II has Palaces rather than dungeons where you need to beat the boss to get to the shrine to place the crystal. This is done to wake up a sleeping Zelda, who has been asleep for many generations according to Impa in the manual. As Impa put Link to the task once he was ready (maybe Link has been sleeping until he is ready as in Ocarina of Time), it wouldn't be too far of a stretch to make Impa put Link to this Sheikah mission now that Impa has been associated with the tribe. The bigger world would allow for more shrines, both worlds have "free travel" in a sense, and both seem to have an emphasis on a primary character waking up. Could this just be a coincidence, a form of inspiration for the game, or is it possibly a remastering?
