I already placed the fishing quay between the dyes and the pearls and planned to harbor out to the nice market spot. The game made me complete the quarter before I could start a new district, and after that, I could place districts like normal. This is a town, so it's not like there's an empty district I started building on that needs to be completed first.
I feel like I only ever build walls for the tourism in exploration or if I have bonuses to walls like with Charlemagne or Normans. Don't tend to build them in the capital because by the time I have production to spare, it makes more sense for them to be in the frontier, but you have to purchase them in towns. And that's if you have the foresight / aren't too greedy that you actually buy them in advance, because you can't purchase them while under siege from what I can tell.
Just wanted to know if I'm missing out on some value somewhere, or cool ways to play that makes more use of the mechanic.
Captured settlements retain their previous leaders' abilities. It's Ashoka's settlement, and it looks like it's giving me his +1 happiness adjacency for improvements. (It's actually +2 for reasons I don't understand.) This happened earlier where I went to build an altar in Lafayette's Paris, and it was going to give me 6 food. That was his Pantheon bonus, but it also gave me my Pantheon as well.
I think I'll build the Pyramids...
Idk if there's an oops-all-rivers map type, but I did choose random.
