One thing I was pleased to see is that you take a diplomatic hit with your rivals for aggressively expanding your influence over city-states just as you do for taking a huge tech lead, settling land near them, building a large military, or any other threatening action. I lost a very profitable trading partner in Rameses when he cut diplomatic ties with me for allying with Brussels, which he considered within his sphere of influence. I've had to do a lot more diplomatic tap-dancing with my rivals in this game than any other round of Civilization I've played over the last two decades.
