City-States

City-states are coming back from the last two games! Except this time, I want it so you can play as them. In vanilla, there are 6 city-states for each type: Militaristic, Cultural, Scientific, Religious and Industrial. In any of the expansions, you get 8 city-states instead of 6 for each type. They both add Economic, which used to be called Trade. Magical Lands gives us Maritime, which shows up in Civilization 5, and is in a scenario (Path to Nirvana) in Civilization 6. Finally, Across Earth gives us Exploration. You can send envoys, which give you different bonuses. You can ignore them, and carry on with your game. You can go to war, and gain a city. You can levy their military if you are the Suzerain (leading envoys). To levy a military, means you control their units for 30 turns or until someone else becomes Suzerain. You will have to pay Gold. These tables will have the names, their countries, their expansions, and if they replace, get replaced by, or won't be in a game with a civ.
