Intelligence from the AI!

[Ansar]

Sometimes, the AI actually does things that impress you (more than often not, but still...). Post here any that have caught your eye and you just think "Wow, did the AI actually did something smart!".

I'll start: In my current game, the Russians actually made a settler factory!

I may be wrong on this one but I think Alex set up a trade deal with me to avoid getting destroyed. From out of nowhere, he asked me into a trade deal. I know that the AI knows where every unit I own is located so he knew I was amassing troops on his border.

this may have been happenstance but it just struck me as odd. I use that same technique to keep AI from declaring.

What say you all? happenstance? or smart thinking for Alex?

I posted a picture in the screenshots thread of a time when the Japanese made a naval blockade of my beachhead town, cutting off the dyes that I had just conquered from them.

I wouldn't rely on that. The AI don't care about broken reputations when trading with each other.

Well, if you didn't want to break your rep, yes, it was smart.

They don't care about their rep but they care about the spices. Their little people don't like it when you take away the toys.

Hmm, there clearly is some learning process in the AI. I have boosted the yield of coastal and sea tiles, so that a single tile island now is a viable spot to locate, and now the AI is putting cities on those single tiles. This does make things tough, as the only two units that can attack the cities are the berserker of the Vikings/Scandanavians and the Marines, shows up at the end of the Industrial Period. With this being almost the last city of the Aztecs, it is going to be a while before I can attack it, as I am playing Byzantines. It keeps generating settlers and sending them out, so this is turning into a real problem. Not the first time that I have been hoisted by my own petard.

AI plants a 1 tile island city in an AW game, thus guaranteeing survival at least until marines. Possibly clever, possibly just luck. Also the times when they put a fort on a 1 tile choke and put a good defender there.

The AI will settle where there is open land and open space (land/sea tiles) of at least 5.

As for surprising AI moves, in my current dominantion/conquest only game (all other VC unchecked) , I was amassing an army of Samurai and Crusaders ready to attack the Mayans and I was attacked first in a sneak attack. They tried desperately to take the city where I had my invasion force being prepared. Certainly not one of the less fortitied towns, but it shows the AI does pay attention to troop buildups.

In the same game, Spain, a tiny 12 city fiedom wedged between their more massive neighbours the American and Egyptians went Fascist for the unit support.

Well, I thought that Caesar was doing something smart in my last game... He built the UN, and the vote was tied 3-3, so he went and eliminated one of the civ's that voted against him, which seemed quite intelligent. Thought he'd win the next vote for sure.

Then, several turns before the next vote, he declared war on one of his allies, which triggered several MPP's, so suddenly the whole world hates him. Three turns later, I launched.

Once I was playing as Rome I was in the modern ages everyone else was just getting nationalism. I had two lanbridges under control each on one side of me. I also had two enemies there. They both signed mpp then blockaded the bridges with rifles so i couldnt invade them as easily. (i was amassing troops)

I am wondering if there might be a RNG working with respect to some of the AI decisions, as sometimes they do something quite good, and then very shortly thereafter, something quite stupid. In a 31 City-State game that I was playing, I invaded and took the Arabs town, knocking them out of the game. The near-by Persian capital immediately launched an attack of the newly captured city, which I had made sure that I had enough troops on hand to handle. Not bad performance, as immediate counterattack against an amphibious landing is good tactics. A short time later, I have a nice stack knocking on the door of the Ottoman capital, when all of his troops come pouring out past my stack, heading for another city that I had taken while earlier. Only a spearman was left in defense, and he died very quickly, along with the Ottoman stack when the capitol was taken. Very bad tactics. Because of the range, I am wondering if there is a large list of possible actions for the AI to take, with the likelihood of each action being a probability. Depending on what the internal RNG results are, that determines the AI action. Any one have any more information on this?

The Americans launched a naval invasion. That's not the surprising part though. they were allied with the Spanish, and the same turn the Americans landed the Spanish bombed my army into oblivion from bombers based in an aircraft carrier, resulting in me losing that city. Who would have thought the AI could coordinate attacks? And who knew the AI used aircraft carriers? Damn I was surprised.

 

[axehaxe]

One time the Romans did something that is probably the smartest human thing to do! I had modern armors in some cities and suddenly, mass artillery was being used on MY MODERN ARMORS!! Furthermore, then the Romans used cavalry to take out the redlined units!! It was one heck of a surprise after all those years that the AI DOES know how to play...at least once in a blue moon.

 

[dexters]

The AI can use carriers.

A lot of times, the AI only looks crippled in the modern era largely because of the size of the footprint of the human player.

Most players can easily be trading around techs for 300-400gpt per turn cumulative from all the civs. That's a lot of units the AI can't support because they are broke and paying the humans large gpt and also udjusting science slider down to afford their maintenance. It's a deathspiral.

had the indians do a naval blockade on my city that was there solely to export coal
