I have this idea brewing in the back of my head and I wanted to write a bit to see if it can come out more. Immigration is such a cool part of Colonization and I feel like we can expand on it in cool ways. We are still using the basic system from vanilla, but... At the moment players start out from land and until you discover a village immigrants come from "a far". I am thinking that we cut the initial immigrants that come from unknown distant lands and make it so they can only come from native villages. This would encourage exploration and also making friends with your neighbors. Then when players build a certain level of Dock they can start to get Immigrants from around the 7 seas. The types of immigrants will be determined by the types of Trade Routes you have discovered. Like some immigrants would be unlocked when you discover the Spice Route. This would give two options for receiving immigrants. And you would have new Civics/Buildings/etc that increase the frequency/types/costs of immigrants. This would add more things for the player to unlock and could be fun doing it. This is just some initial ideas, but they seem to be promising, any thoughts?
