maybe I should add this to my sig?
 
I was also about to post the same as Level did. AI galleys DO NOT CHEAT!!!! You can remove that from your list, theNiceOne.

Galley teleportation has been proved, but is a bug, not a cheat, since the human player can take advantage of it, too.
 
Wonder production
The AI is suspected of knowing how close you are to finishing a wonder.

I highly doubt this. Everytime I´ve investigated rival AI wonder producing cities and adjusted my production to beat them to the wonder, I have won.
 
I haven't seen anything myself to suspect that the AI has any special knowledge regarding wonder building, but I have seen some resports saying that they were beaten by a turn or two, the reloaded 10 turns back, micromanaged to be finished 3 turns earlier, and then still being beaten by a turn.

This can have (at least) four explanations:
1) Outright AI wonder cheating: I'm pretty sure this is not the case as this could be easily discoverd by investigating the enemy city.
2) AI could be cheating and knowing when you would be finished, and then micromanage to complete it before you.
3) There could be some other factor that just happened to make the AI complete the wonder faster (like not getting a disiease the second time)
4) The player reporting this could be completely wrong.


Personally I'd go for 3 or 4, as the AI don't seem to micromanage cities much in any case.
 
ainwood, I seriously doubt that the AI ever investigates any human players cities. The AI don't seem smart enough to ever think about whether it has a chance to finish a wonder. It'll gladly start it 40 turns after another civ has started the same wonder.

I seriously doubt that there are any cheats involved here though.

An alternate explanation is that the AI gets the equivalent of a "pop-up" like warning announcing that the annoying human player has started building a wonder (just as we get pop-ups regarding AI wonder starts) -- a sooner human start may very well prompt a sooner AI start and could well explain the "I reloaded, started sooner, and still lost it!" complaint.
 
Maybe this will explain something:

I noticed that i often get the msg about an AI wonder completion 1 turn before i complete it myself. But when i check the wonder screen it tells me the wonder was compleated earlier!

This only happens if you have no contact with that civ yet!
 
MAS, now that's cold! I didn't know that. I guess they at least give you that 1 turn to swap it over. . . they could just not tell us (which would be more realistic I suppose).

TheNiceOne, this is great. Thanks for trying to consolidate all of this.

Now, I'm new, but there are a few things I'll mention.
Maps-exploration: I know there have been several times I've found goody huts or other things of interest quite near to AI cities that they never managed to find.
Maps-resources: It is claimed that the AI knows where resources will pop up in the future . . . isn't the same true of custom made maps so that the player knows where everything is? The same would hold for world maps. . .we know exactly where all the land is and isn't.
Settlers: I've seen them stockpile as well. I think part of it is that they churn them out during early expansion but because the human (and other AI's) are settling as well they have leftovers with no place to go. The other part is probably just planning for future opportunities. Not a bad idea actually.
Wonder races: We can check to see how they're doing, why can't they? (Whether they actually do or not is another matter.) Maybe they switched off from something else to win that particular race? I know I see them switch wonder production constantly every time one gets completed or looks like it's going to beat them. Or what MAS said :0)
Battles: Yeah, I've seen some pretty ridiculous ones, but it happens, and it's not that often. I had a swordsman that fended off a small stack of cavalry too, so hey. When people lose, especially unexpectedly, the first response is generally to cry foul. They just forget how cool it was when it worked in their favor.

Now, I think the diplomacy is all screwy to begin with so I would have no idea how to gauge whether AI-AI reactions appear "fair" or "right." My advisors are always telling me that the people I just took 10 cities from are my friends, and in trades I am consistently accused of having betrayed people I've never even dealt with. In any case, if the AI is too friendly with AI's it shouldn't be friendly with, it appears to at least be screwy across the board with no disctinct advantage (other than we know who our "friends" actually are).

Just my thoughts

I don't know if it's just a coincidence, but I notice the following:

It happens generally at the beginning of the games, when Im building settlers and founding cities.

I'm on a map with 2 or 3 more civs and they are building their cities too. So I see a good place to found a city and then point my settler to there. But one turn after it, guess what, the AI found a city on the exact place, as if they knew I was going to find a city there.

It happens in my games sometimes. Any ideas?

The AI can also knows which spots are most favorable for their cities so it's no coincidence that you and the AI both chose the same spot.

the AI DOES investigate cities especially ones that are building wonders. i got the theory of evolution and got electronics, starting the hoover dam right after. the persians managed to sabotage production in that city b4 the spy was caught.
 
Think about this: What if the AI actually MINED grassland tiles? you'll notice that esp in the early game grassland tiles are almost always irrigated, which is useless until a new government is installed. Just imagine how tough the game would be on Regent (let alone Emperor and Deity) if the AI acutally mined tiles! Now that's a frightening thought...
 
Exanguination - What?

But the AI is *always* mining grasslands over here. In fact, I never stopped to think about how good an idea it was until I saw them doing it...
 

However, later in the game when you abandon a city leaving an empty space AI starts to move to it with the typical settler/defense unit combination. How can they know? This looks very much like cheating.

I don't know if that's AI cheating, or not. The same thing happens on the human end of the game. Just recently I was nuking the living "H" out of an enemy civ. Just by examing the world map, I could see that it was rebuilding roads, clearing pollution, etc, even though my closest unit was across an ocean.

The AI, much like the player, is privvy to knowledge that it probably shouldn't have.

IIRC, they mine normal grasslands and irrigate all bonus grasslands (assuming they have access to water). I have taken size 12 enemy cities, that had say 3 mined squares and the rest irrigated with the result of producing 10+ wasted food that could instead have been 10+ higher production.

This should really be improved by Firaxis. Shouldn't be very difficult either.
 
TheNiceOne is correct, mostly. At least from my experience, the AI always wants 3 food from a tile. ie. it will mine wheat/cow tile but irrigate grassland andplains. Most of the time, however, it will mine normal grassland, but I have them irrigate normal grassland (its not rare). The point I'm trying to get across is even without the cost depletion on higher levels for the AI, if they mined tiles (think of RRs: 2 EXTRA shields for every grassland tile neach city the AI holds), keepingup with wonders and infrastructure would be hell
 
I have noticed one more cheat from my last game:

Espionage, this is what Gandhi did to me:
1. Destroied my wonder production everyturn
2. Destoried a factory production in one of my cities once every 3 turns
3. Uncover my spy the next turn after I planted one.
4. Steal my map once every 5 turns.

Where did he get all that money? It is not cheap to do any of these for a human player. This never happed to me before 1.29f
 
It's funny to still see these issues being hashed, when they've been documented by Firaxis! But I guess it's been proven that folks don't read FAQs :)

Anyway, knowledge of the map and resources has been confirmed by Firaxis. This leads to a couple behaviours:

1) It will found cities in locations to get strategic resources, and it will favor those locations when deciding where to found next. In other words, it will found these cities first.

2) The AI knows of all viable city founding locations, and is programmed to spread like a weed, so it will build a settler / defender combo for all the city locations it has "in mind". However it is not "allowed" to use the inherent map knowlege to go found these cities until it has explored these lands, which is why as soon as you sell your map, you'll see settlers (which were already built) heading to the 1 square you don't yet control. If you plant a unit at that square, you'll see the settler turn back too! In other words, the AI ends up with surplus "pre-built" settlers.

3) It will value a city with a strategic resource, even one ages away, more highly when being extorted for peace.

4) The AI doesn't "know" where you are going with a settler in order to beat you to it. What it does have is a plan as to how best to lay things out (see above) which it is following. It just happened to beat you to this particular site. If it had horses or iron visible, you shouldn't be surprised at all!

Cheers,
