So I have been thinking of a way to represent the different types of empires in history and make managing your empire more interesting. There would be no barbarian camps or city states. Instead, everyone would start as a "tribe", 1 settler ready to found your first city. So the game would have more AI "tribes". Each tribe would have a unique bonus that would stay for the whole game and apply to individual cities you settle. If you conquered another tribe or convinced them through diplomacy to join you, those cities would keep their unique tribe bonus. So through conquest, you could have cities with different unique "tribe" bonuses that would apply to the individual cities. When your capital grows to X pop and if you have not settled another city yet, you would become a city-state. You would pick a city-state unique bonus that emphasizes tall play. When you settle your second city, you would get to choose whether to make that second city part of a kingdom or to let it be a city-state allied to you. If you choose to be a kingdom, you would get direct control over the second city just like a normal game of civ and you would replace your city-state bonus with a kingdom unique bonus that emphasizes wide play but getting too big would give you a small chance of the cities rebelling against you. If you choose to let the second city be an allied city state, you would not directly control the city's production but would get to trade with it, controls its military units in times of war and it would automatically declare war against your enemies. You would become a League and get a unique league bonus. You could settle other cities and make them allied city states as well and grow a league of several allied city states this way. At any point when you settle another city, you could declare yourself a kingdom. Your capital and that city would become your kingdom and any other allied city states would become independent city states no longer allied with you but friendly. The League would be dissolved. You could conquer these city stated to forcefully integrate them into your kingdom or through diplomacy pay them to join your kingdom. When you conquer a city that you did not settle, like a city from another civ or a foreign city state, you could declare yourself an Empire. You would replace your kingdom bonus with a unique Empire bonus that emphasizes conquest and expansion but there would be a higher chance of rebellion the more different tribes you conquer. You could make other tribes or kingdoms your vassal like in civ4. Later, in the game, if your empire gets too big, you could declare yourself a confederation and replace your empire bonus with a unique confederation bonus that would also reduce rebellion. When you get the "nationalism" civic, you could declare yourself a nation-state if you wanted to. You would automatically lose cities far away from you but your remaining core cities would become more powerful and have a strong loyalty factor. You would also replace your empire or confederation bonus with a unique nation-state bonus that would apply to all your cities. Also, if you are a peaceful player that does not conquer, you could build a big League and then at some point change your League into a Confederation and skip the empire phase. Thoughts? I feel like something like this would really make a civ game more interesting. It would give the players interesting choices and interesting bonuses. It would also be really cool to see your civ evolve from a lonely tribe into a small kingdom and maybe into an empire and then eventually become a nation-state or stay an empire if you want. It would be up to the player. But it would make the history of your civ more interesting, I think. Plus, it would make the game a lot more dynamic as different empires around you might become empires or break up into nation-states. Instead of always encountering a neighboring "civ", your neighbors might be an AI league of city states or an AI empire etc... I am hoping that city-states, kingdoms, empires, confederations and nation-states would have different play styles so that the game would feel different based on what you are. I also envision a civ game having a lot more starting AI "tribes" in a game so that on a large map, over time, you could encounter city-states, kingdoms or other empires.
