Do AI's suffer war wariness?

[SkiRich]

I know I suffer it when I launch wars, but dang, one Civ I am watching must be at war with a city state I have surrounded by armor for more than 60 turns already.
The only fight they can muster is from a sub two tiles away, which the city state has so far been able to recover from since none of the other units can reach the city center.

How can a an AI be at war for so long without suffering some issues at home?

[tempest.of.emptiness]

War weariness is not just a function of time but also of actual conflict. If neither side is actually fighting, there is little to no war weariness accumulating. This is true of player civs as well. I had a game a week or so ago where Kongo went to war with me as part of a deal, but was on the other side of the planet. They didn't like me for other reasons, and so didn't have an interest in asking for peace. The war continued for at least 200 turns without anyone firing a shot, but I never had any war weariness. I assume that they did not have any either.

War weariness is caused by combat and by units dying. It degrades over time, much faster if you aren't at war with anyone, and a very sizeable amount will be removed when you make peace (including city state allies of the enemy civ).

Does abandonment of wonders, consitiutes a sign of readiness and weariness?

I had Alexander compete me on Oxford University once, I won out eventually in a surprise.

I repeated many attempt on that wonder after many repeat attempt to boosting it still fails...

Then it snaps!

If I raise the entire world have everyone to fight against him alone, would he instead go direct his effort towards war until he eventually gave up building that wonder.

And surprisingly it works he simply cannot focus on wonders due to the war, what amuses me more was he was never the same after that, no more wonder building just pure warmonger with all its surronding neighbours.

War weariness has nothing to do with this. It's a mechanic that causes amenity penalties. Which Alexander literally doesn't have to deal with in the first place.

Interesting, care to elaborate more on this penalty? I am rather new to this game. Thanks

Other than what was already said, war weariness can actually reduce while in war if no units are fighting. You take the biggest hits from losing units outside of your cultural borders or from losing tiles to pillaging by foreign units, and lesser just from each combat. There are modifiers, like fighting Gandhi is higher valued hits, any combat during surprise wars or formal wars are higher hits, firing nukes is the highest hit in the game I think. Some policies reduce by a percentage, retiring admiral Lisboa will reduce it a percentage. Alexander never suffers a war weariness penalty because that is his unique ability.

War weariness accumulates and nets a hit to amenities, where amenities are generally how "happy" your population is, kept afloat by luxuries, entertainment and water park districts, policies and specific religious beliefs. If your amenities fall below -3 there is a % chance each turn of spawning insurrectionists who will attack whatever is near them, and that % increases as you have further negative amenities. Also, you lose income/production from lower amenities.

I see, that explains why my people are so unhappy as of late...

I practically nuke every city I attempt to conquer.

Yes, that would make your population unhappy and you'd need amenities in some form, or policies or other means to reduce war weariness accumulation by % like propaganda and/or martial law which can stack for 50% total reduction (total -75% with retired g. admiral Lisboa) going forward (not retroactive) or defense of the motherland (specifically 100% reduction for combat within your border)

Also, while on the subject of amenities, multiple luxuries do not stack. 2 silver isn't useful, trade one of them away. Most luxuries give 4 amenities, a few give 6 (perfume, cinnamon, clove) but these will be split among cities +1 each. That's just how they're distributed. Some amenities can be more targeted as entertainment districts and buildings, certain religious beliefs, some tile improvements, some retired great people effects.

Here is a good reference for amenities.

oh, and, to your original question, yes, AI suffers war weariness just as you do, unless the AI is Alexander.
