hello. i wanted to necrobump this thread. i was searching for sth else and then i just noticed this.
most of the time, colony option is underestimated. the most imp function is that, you can cover a large territory under your influence by this way.
1) how to build it:
not only a different landmass but also every island that you can build 2 cities can become a colony. so even a very small island is enough. just press F1 and liberate
after you build a colony, if you settle on another new island, you can build a second one.
the only limit is #of players that the world can have. it's somewhere in the code, yet i never changed it. i think it was ~18 for huge and less for smaller planets.
2) How to expand it:
it's also possible to liberate new cities to your colony, which means making them have more than
2. so let's assume
* u have a huge landmass, much free space to expand
* u don't want state property (which is very powerful)
* u don't want to have more cities
in this position, you can use colony option. building a new colony in the same continent of yours is not possible but gifting a city to your colony is possible
so you can fill in all the continent and gift it to the colony. as long as you can control the colony by means of politics, it is no problem. besides, if you have more than 1 colony, you can gift a few cities to colony civ1 and gift more few cities to colony civ2 and so on. so practically you can cover everywhere as you like.
if you have many units and you have regretted having so many of them, gift them to your colony instead of deleting (if you don't want a war neither).
3) How to trade with it:
you order it what to research. you get resources and techs from it without giving anything in return. but of course after a few trades, the colony will start ignoring you. but still if you get even 2 techs from colony, is it bad. if there are some techs you have left behind, you sometimes don't want to waste even 2-3 turns right, bec most of the time there is a tech that you want urgently. so ask your colony to research that tech. they can get some small techs.
4) when to build it if you want an effective trade partner:
colonies are like barbs. because they are very less civilized. they can't behave cleverly, not even close to an AI. the earlier you build the colony and the more cities it has, the more AI-like and AI-wise it becomes. so build it as early as you can.
5) inside the game parameters, it can have even more positive effects maybe, i don't know.
6) still, i would also like the colonies to have more effect on game.a little more boost could be fine.
For example a trait or civic might have been made correlated with it just like below:
IMP trait: gives 1free GG per each vassal (only vassal, not colony)
gives +1 great person (great merchant) birth rate at the capital per each vassal & colony
strange it would be
