Best free "city building" games

GAME GENRE – City-building games are strategy games that put you in charge of creating, expanding, and managing a settlement, town, or entire city. You usually start with little more than some empty land and a limited supply of money or resources, then gradually build roads, houses, public services, workplaces, and other essential infrastructure. As the population grows, things become more complicated: citizens need jobs, food, entertainment, transportation, and somewhere to live, while the city's economy has to keep everything running. Some games focus heavily on realistic urban planning, while others add historical settings, disasters, politics, trade, or even a touch of fantasy. Popular non-free examples include the SimCity series, Pharaoh, Caesar, and Cities: Skylines.
