Something that's been driving me crazy for a while that I just finally figured out: WW Hyrule Castle looks nothing like OoT Hyrule Castle, right? Well, I realized that's because in OoT, the castle was destroyed and replaced with Ganon's Tower in the Adult Timeline. So they were able to rebuild it before Hyrule was flooded - and of course they couldn't make it look the same as it used to be!
