Started a 5069 World Map game (Armenia), and I'm somewhere mid-late Renaissance right now. AI behavior in line with what's been described in the past. France wiped out early, Germany a bit later. Netherlands a dominant force early but seems to have faded. Portugal still the tech leader (though I'm getting close or maybe just passed him) and was doing some kind of One City Challenge thing until about 700AD, and just built its third city a few turns ago (on the N American east coast). Berbers seemed to have had no problem steamrolling Carthage.
It's not a "some kind of One City Challenge thing". Netherlands, Portugal and Israel are city-states, and can't settle new cities until Renaissance. Netherlands got permanently removed in 5070, as without them Europe seems to function somewhat better (at least I don't see France and Germany die every game).
I'm a little mixed on Alliances. It sounds like a good idea up front, though you get a snowballing effect on the dogpile behavior. Early game, it was all of the full nations wiping out the African minors. Recently, they genocided Spain which had been underperforming. I don't know what recourse you have when 10+ nations simultaneously war declare because one was in a bad mood and picked a random fight.
It looks like 5070 has good potential, I'll probably start a new game and see how it changes the above. I'm not sure about the alliance-dogpile effect, though changes in how the AI picks fights may temper it a bit.
Well, in 5070 AI is more picky both about alliances and about declaring wars. Should lessen the alliance pile-ups somewhat. And yeah, since it is a new feature, there is definitely some more balancing to be done. We're working on it.
Just out of curiosity, how does it work if an Alliance would force you to declare war on one of your own allies? A allied to B & C, B declares war on C, what does A do? Or A allied to B & C, B allied to C&D, A declares war on D, C would go to war with A but what does B do? There's a lot more permutations, especially on the World map.
I actually don't know, but my guess would be that defensive use of alliances gets priority over offensive use. So in that case, A would come to C's aid in your first example.
Related Alliance question: Does the AI have any clue on how to exploit Alliances (I'm struggling as the human to figure it out)? I still get typical AI behavior when a "friendly" leader will dial me up before starting a war to try to suck me in (I almost always refuse, as it's generally not worth the trickle-down relationship hit with all of the target's "friends"). Then, the next turn, I'll be drawn into the war regardless because of our alliance, effectively mooting my refusal.
Well, AI doesn't really seem to know how to exploit basically anything. Once you peer under its hood, especially when it comes to diplomacy, most AI processes are pretty simplistic when it comes to planning and execution, and most are just probability-driven.
A quick answer to my own question: I suppose that the (Realistic?) best defense from being dog-piled by allied nations is to be in many alliances yourself. Of course, this is of no help to the minor civs who won't open borders or ally with anyone, and thus invite a world war every time the massed civs attack one.
Well, minors are supposed to be cannon fodder. But we'll be trying to introduce more diplomatic relation variables that will lead to less alliance sprawl, and more dynamic alliance system as a whole.
