City Capacity in Humankind determines how many Cities a player can have without incurring any Influence penalties, and starts at 2 when they first enter the Ancient Era. While some fans may expect that number to increase automatically when they enter the Classical Era and beyond, that's not actually the case. There are ways to increase City Cap in Humankind however, though they can be a little difficult to find.

That said, if a player is earning a reasonable amount of Influence, they may want to sacrifice a bit of it in order to expand past their current City Capacity.
