I would like to add my 2 cents to this forum from a Newby trying to wage a warmongering island campaign against the biggest bully in my world (the Aztecs).
I had my first "what the bleep, I hate this game" moment last night. I finally made a beachhead in Aztec land with a settled fort city and miltary units and had captured one of there size 6 cities, even had one of their allies (the Iros) give up and offer me a peace treaty (everyone other CIV still hates me), I had the galleon/caravel convoys going with new units and was feeling pretty good THEN I had civil disorder in all my cities (shutting down my production), followed one turn later the Iros joined the French (2 turns after our peace treaty) to attack me (my foreign advisor says they had an MPP). and worst of all by my fort city flipping to the Aztecs and I think they call this a culture flip. What amazed me was that I settled the city and had a Leader in the city, one turn from barracks, and worst of all had just drop off 7 units. I assume all my cannons, knights, legions and musketmen in that city are now Aztec units. This represented half my invading army.
Questions
Aaaaannnndd . . . welcome to the wonderful world of culture flips. Sorry to hear about it. Though it may be no consolation, most if not all of us have lost troops to culture flips. I remember losing a cav army (or was it 2?) to the Sumerians in a culture flip once.
1. I don't really know what I'm doing when their is civil disorder on the hhome front. I just increase my entertainment spend to 20% and wait. any better methods?
30%? One of the issues that you may have run into is War Weariness. There's a War Academy article
here that may help explain this better than I can.
Also, he basic rule is that a city goes into civil disorder any time that unhappy citizens outnumber happy citizens. Neither content citizens nor specialists make any difference in determining civil disorder. Example: A size 9 city with:
5 happy and 4 unhappy: will not riot
4 happy, 1 content and 4 unhappy: will not riot
2 happy, 5 content and 2 unhappy: will not riot
4 happy, 4 unhappy and 1 specialist: will not riot
3 happy, 2 content and 4 unhappy: will riot
Just count happies and unhappies. If you haven't located them, there are some "popheads" in the downloads (I think that's where they are) that will put mood badges on your citizens & make them easier to count. I use some that have a green badge for happy, white for content and blue for unhappy.
2. Did the fact I had been waging a war for umpteen turns cause the civil disorder or is it chance?
See my preceding answer. War weariness may have been a factor. What government were you in?
3. Culture Flipping - I assumed it could happen in a captured town, but this was my settler and we were starting to win to the point where the CIVs where asking for peace treaties and I was getting greedy. What can I look for to know when I'm vulnerable to a culture flip?
Culture flips can happen in almost any town. The exact dynamics are a little unclear to me, so I'll leave that for someone who knows more than I.
Hint, Hint, Hint!
4. Because of the flipped city, and my perception of its military strength, I'm ready to quit the invasion. Should I be able to get a good peace treaty out of giving the Aztecs back their city or does the AI know I'm stuck and I should be happy with anything they offer?
It depends and I don't really know enough about your particular game to say one way or the other. Go to the bargaining table and see what they'll give you for peace.
5. Any chance or method to make my fort city flip back to me?
I rarely build much culture so it never happens for me, but maybe one of our resident culture-mongers knows of a way.
