Era After anon here. Still busy with things, but now that there's a small lull for me, I might be able to craft more lore. I've been just finished a book about the Bronze Age Collapse and now rereading another book about the fall of the Roman Republic, so the ideas I've taken from those books about the world of the Era After are swirling around in my head. But before I do that, I'm wondering if I should try to flesh out the entire world before moving into sections of it rather than make up the world as I flesh out specific sections of it.

I see pros and cons to each approach. The pros to building a whole world before focusing on regions is that I can construct a "world state" in the way of knowing what goes where, and that I have a general outline that makes it easier for me to not contradict myself or make things vague. The downside to this approach, however, is that the map is more "set in stone", and wouldn't give as much room for future lore developments in the nations of the main timeline regarding regions and such. Not sure whether to keep my old approach or try a new "global" approach as I've described it. What does everyone think?
