Everything sounds awesome except the prologue. That's too long for pre-action in a game, and the acting in these things (Wing Commander 3, 4, Prophecy not withstanding) are always terrible. Also, Link shouldn't talk. Everything else I hope is true, especially the two overworlds idea (with Hyrule in ruins).
On the Ganandorf as a child, I actually like the idea. I could really dig the evil magician and then using Ganandorf as a the real villian, similar to that trope, revealing him to be the one who actually turned Hyrule into the hell world.
