I think it's really weird how ethnicities in colonizable provinces simply vanish once settlers arrive. I think a simple solution would be to keep a colony's ethnicity as that of the colonized province until settlers outnumber the natives-
Very good idea. This leads to below.
That's a very good suggestion.
It should probably work like this: You need 1000 settlers to complete a colony. If the province has >1000 natives, it keeps its old culture, if it has <1000 it flips to your culture. I just don know what happens, if there are 1000 natives.
I think this is the beginnings of a calculation, however...
Or have some flexibility. For example, you could get a bonus to colony growth and reduced native aggression/ferocity for maintaining the native culture, or stick with the current rates to get your culture there (or penalties for your culture, whatever works better balance-wise). Ideally, this could be on a province by province basis, so that you could decide to focus your culture on the more important provinces.
The idea that ferocity and aggression play into which culture becomes dominant could also merit thought.
If colony pop > 1000 and ferocity < 5 and aggressiveness < 3
Then colony_culture = primary_culture
Else colony_culture = province_culture
Or
If colony_pop > native_pop and ferocity < 8 and aggressiveness <8 //provided that crushing rebels increases either ferocity or agression//
Then colony_culture = primary_culture
Else colony_culture = province_culture
I can't remember the specifics... when you attack the natives, does it raise or lower either aggression or ferocity? Because that could really play into this mechanic. Either way, if you crush the natives to lower their population (and thus make your culture dominant upon completing the colony) it should raise aggressiveness or ferocity and make culture integration harder. Aggression and ferocity should be on count down timers from the moment a nation starts colonizing, and colonial completion should require clicking a button (to give the player a chance to cheese and avoid taking native cultures if he really wishes).
When you add in colonial events like the penal colony - that should add to ferocity or aggressiveness and affect cultural integration as well. This area of the game is ripe for expansion.
The game does do a bit of a disservice to the cultural game, particularly for native cultures. They may not have organized along national lines, but native peoples did organize along cultural lines. Good thread.
