While reading the amazing game "slow and steady wins the race" by Seraiel he performs this amazing move where he gifts music to force an AI to kill a great engineer on Sistine instead of MoM (which he is aiming for).
This suggests that AI's have a wonder priority. Is there a list of the priorities anywhere? I'm wondering if its a viable play (for example) to gift an AI early stone to try to get them to build mids for you while you just make the troops required to take the city with mids. But it kinda depends on how valuable mids is to the AI.
Thx for the compliment first
I know from AI having different Wonder-priorities, as I've played a lot of games lately, and some Wonders always get built real fast, some get built real slow.
Wonders that the AI prioritizes heavily are:
SH (almost impossible to get without sacrificing a lot, anyhow, this wonder get's built so early mainly because many Civs start with Mysticism)
Oracle (get's prioritized highly, I've seen AI's chop out the Oracle in 10 turns (Marathon speed where 1 chop = 9T) anyhow, the tech Priesthood doesn't have high Prioirity for the AI)
Mids and the GLH also always go early, if one keeps in mind that the Mids are extremely expensive and that the GLH is almost as expensive because it doesn't get fastened up by a Ressource. Latest Mids I've seen were 1500 BC, latest GLH must have been somewhere around 2000 BC.
Then come the 3 Aesthetic Wonders, from those I know, that Shwedagon Paya has a higher Priority than the Parthenon, or, more Civs start with Gold than with Marble, both possible, but Shwedagon always goes shortly after SoZ, which costs a lot less Hammers.
I know sixtine has one of the highest priorities for the AI, as does the Colossus, those get built lightning-fast. In contrast to that, the HGs, the MoM, the Hagia Sophia and the Chicken Pizza get built slowly, but those are again crappy Wonders (excluding the MoM, that one is the most awesome early to mid game Wonder after Oracle, HGs are good on Huge maps) .
AP also get's built slow, but that might again be because it's twice as expensive as the Mids, because it doesn't have a specific ressource.
I know from AI, that having a specific ressource hightens the chance that they build a Wonder sped up by it. I know that, because I've seen the Taj Mahal get built in 10 turns by Civs having Marble, and I've seen Civs not having Marble not even starting on building it for 20-30 turns. Might again be coincidence.
About the late game Wonders I don't know, most times my games don't go that far or I'm so far ahead that I get the Wonders.
Maybe you can find out for us? Woldbuilder an AI, give it all techs, gift it some GE's one after another, look in which order they build the wonders?
Indeed, that is a question that tickled me too, but without the code reading keen ability, I let down the questioning.
But wonder building is a pretty random thing that varies a lot in different attempts of the same maps. Sure, each leader has its own probability of wonder building. Louis XIV and Ramesses have the highest odds (yes, HC has lower odd than those two, I was surprised too) while Genghis, Shaka, Monty (e.g. ) have the lowest.
Why Freddy prioritized Sistine Chapel over MoM? I can't say for sure, but perhaps he was starting the wonder and a hard-coded script forces the AI to rush wonders that haven't been invested at all over those that are already half done.
You don't believe me
I've just loaded the savegame where I did that move again, and didn't gift Freddy Music. Look what happened:
No joking, I know that AI has Wonder priorities. I. e. the GL always get's built with medium speed, while the HGs and the MoM get built slowly and the Shwedagon Paya gets built lightning fast. With 17 AIs in my games, the variance concerning wonders is very small, as someone always decides to build it. Interestingly enough, I do believe though, that certain AIs have even specific Wonder priorities, otherwise I cannot explain why Frederick always gets the Mids in my games. Yes, he has Stone, and Roosevelt and QSH are also hot candidates, but I've seldomly seen Louis or Ramesses build them, those two may be hindered by SH.
And concerning your point that AI doesn't prioritize Wonders where players invested hammers in: cseanny also assumed that, I don't know, as I have no proof of that, but again, I didn't test it.
This would be a perfect task for our friend DanF
Perhaps the AI is just getting more hammers from the engineer for the Sistine instead of MoM.
Good point. Maybe they coded something like "cheap wonders, worth less, lower priority, expensive wonders, high value, high priority" . Shwedagon is more expensive than Parthenon, still, Shwedagon gets built earlier. HGs are cheap, they get built late. Anyhow, MoM = same Hammers as Shwedagon, but get's built late. TGL would fit again, medium hammers, medium build-speed.
