Ugh, you hit the nail on the head with "part of the world." I stare at my map and a perfect spot for a harbor city has NO fresh water source, or I put the capital in a mountain pass that would be a logistical nightmare. You need rivers, roads, farmland, AND it has to look cool. It makes my brain hurt trying to balance realistic needs with a vibe that feels fantastical. I end up overthinking every single dot.
