As someone who is slowly letting CIV 6 work its charm on me, I've noticed something. The Entertainment Complex Arena is the only place where you can see people (represented as dots) interacting and moving about in their seats. I'd love it if you could see little dots on the game's roads, farms, mines, districts, etc., going to and fro. Right now, everything looks like an abandoned ghost town. Even a game like Shogun 2, has little Japanese people moving carts around on trade routes. What would also be cool is if these dots could run away from an enemy one hex away. It doesn't change gameplay, but would make the world look more populated.
