Count me with those who disagree with Zachriel (big surprise to you Z., I know!)
As someone stated, it clearly depends on playing styles. I tend to go to war in the late industrial/modern age. In the meantime I'm perfecting my empire, building lots of wonders, and trading for luxuries to keep my populace ecstaticly happy (and increase my score!) I'm upgrading units, if I got Leo's Workshop which is a priority for me. And when the enemy attacks me, I strike back hard. I assess whether I can annihilate him without overextending myself. Often the answer to that is no until the Tanks/Artillery/Bomber arms combination is available. Not that medievel units can't do it - I just don't typically keep enough of them around for a major offensive.
It seems like the AI starts getting bored with peace by the modern age, especially if we're sharing a big continent. So he attacks, and by that time I'm quite ready to sweep him into the sea. But by the modern age, the cities I'm capturing are
big, and have a lot of culture. And I think that those two factors are probably the biggest determinants of flipping. In a parallel city-flip post I attached a perfect example. Alleghany was captured from the Aztecs, and flipped back to them after 3-4 turns, despite:
- A garrison of 3 mech inf and 1 cav which probably could have fended off the entire remaining armed forces of the Aztec nation;
- A democracy, which prevents him from using propaganda;
- No disorder - 7 happy, 6 still resisting, 3 entertainers (everyone assumes that resistors affect Revolts, but it isn't on the list in the Civilopedia!
- No bordering Aztec territory, as the blitz had already moved on by;
- No particular proximity to the Aztec capital - his was 10 tiles away and mine was 11;
- No corruption - my FP was
three tiles away!
- Lots of improvements, including temple, marketplace, courthouse, and police station!
- 12 smiley faces from luxury resources.
The only things that were "danger signs" in Alleghany were the 16 Aztec citizens, and the
3350 culture that it had accumulated before I captured it! That latter point isn't mentioned in the Civilopedia either, but from all the cities I've seen flip, I think it's key - maybe the most important factor of all.
And yes, Zachariel believes that "all" I had to do was put 10 garrisoning troops in Alleghany to prevent them from flipping. In fact he even proved it with my saved game! One problem...that would be about 1/5 of my continental army...and I had already captured 6 or 7 cities, with ~20 more to go! So I guess I should have saved up 200 extra mech inf or so to use as flip surpressors before starting the war! (Besides the obvious problem with that logic...the Aztecs started it! I'm just finishing it...)
