Good day to you civ friends. Anyone knows what does it mean when adopting Vassalage as civic the +XX free units? Free Units how? Cause I'm adopting it and no free units appear at all.
How does it choose which units to make "free"? The ones that cost the most or the least?
And how does it get X free units?
All units after a certain amount (which are free of amintenance) cost the same, they cost extra in enemy territory.
If I recall correctly the extra maintenance cost (over a low cost civic) is so steep that in fact you will lose money going into vassalage unless you are organized. So you should not go into vassalage to save money (but for the two bonus xp). However it does make the civic almost as expensive as a low cost one, provided you have an army large enough it uses all the free units.
You do have to pay for troops in a friendly vassal's territory. It is easily tested by creating a vassal on a different continent after a war of conquest. Your invasion force that you were not paying for since it was in your (new) territory, is now a huge drain.BTW You have to pay supply as soon as they are outside your cultural borders (I am not sure about cultural borders of vassals), so even in the terrain of a foreign friendly civ.
Does vassalage cancel out the extra cost from pacifism?
Artichoker has written extensively on this subject in his "Leveraging Vassalage" series.
and the answer is...?
I've read some of those, but he seems to use vassalage very little those games. And why would you even want to, outside of some very niche situations?
