Truthfully, Ura wasn't an expansion for Zelda OOT. it was just going to be an entirely new game, having nothing to do with supplementing Oot's gameplay, story, or adding anything to oot. Hell if you look at oot's data, it had partially written data for a forth tunic, 2 more dungeons, and when you connected the DD to Oot it asks for Ura Zelda, the expansion (not new game) for ocarina of time.
so I'm not really caring as much as the le ura project anymore, as it wasn't a restoration, just taking a name under a false pretense and doing their own thing with it. It was amazing, but it got canceled. Truthfully, you project is at the same scale, as its a whole new story and game. Tho you might not be building as much from scratch, you are making a mod for the game that doesn't swap stuff out, and doesn't change little things. You are making new dungeons, but hey, ur not going overboard by using music that is too high of quality for the 64, you arentvusing the MM engine, and you are not inventing new aspects for Zelda OOT that didn't exist in gameplay before.
all that ura had was rewritten OOT gameplay and features, added visuals for show, and uber quality music.
But hey, n hindsight and in scope, it did seem like they tried to bite off more than they could chew. And hell, your project looks great and I can't wait till it is finished!!
