Why won't the AI buy liquor so my units can build?
Yes.
Promotion/Demotion factors. What does the percentage means? How does this percentage is related to the actual number of people promoting/demoting to another class?
They are the relative chances of those promotions. e.g. if you have 3.5% to clergy, 1.0% to craftsmen, 1.5% to bureaucrats then on average 7 months in the year the POP promotes to clergy, 2 to craftsmen and the other 3 to bureaucrats.
The actual numbers are set by different factors which aren't visible in the game (but you can find them in the text files: literacy, CON, unemployment are the most important)
Having had a quick look round to see if anything in the game files looks relevant: You can't; it's hard-coded into the executable.I've noticed that to become a great power you need at least 2 regions. Where can i change that ? Say to 5 regions.
You can't dispose of your monarchy without a revolution, which is actually perfectly reasonable. I'm not aware of any significant wholly peaceful and voluntary abdications in the period 1836-1936.How can I turn a HM's government into a democarcy (other than revolting)? I have developed all the reforms on the political side...
Is there anyway I can willingly leave a nations sphere of influence?
Thanks, but I was not referring to these. I was referring to the ones that appear when you mouse over the number of promoted/demoted people. For example, in my game it says promotion factor: 48% but only one of my 1500 craftsmen promote to clerk/bureaucrat/clergy/etc. every month.
