Yes! I'm working on the Goron Mountain layout today because that's at the top and is a blocker, which is, I assume, the highest priority? And I'll move onto interiors after that.
Also, something to figure out where it lies in priority: dialogue? We've got like 30 NPCs in Hyrule town, so someone or people will have to write their dialogue, and presumably what they say will change based on where you are in the game (so, world's current events), if you've done any sidequests related to them, probably time of day, etc. I figure the best way to organize that would be a bombers notebook of sorts for us to use. Each entry would have who it's about, then their dialogues and what triggers each dialogue. It'd also be a good place to keep track of where the NPCs who move around go.
But yeah, dialogue should be written at some point. And I like the priority list.
