Generally, only missing the Oracle by 1T would make me quit the game. I don't slow-build the Oracle anymore anyhow, so that chance is very small. I usually go directly for Alpha and then I can either trade for the Oracle-techs and chop-whip it or I can at least see, how many AIs have Priesthood, if more than one I'd probably already stop but as I play for HoF, I ofc. try regardless of that, and sometimes Alpha also allows to see if an AI has already started on building it. If having sight on the AIs capital and 2nd city, one can also see via Espionage if that AI started on building something costing many
. It requires training though, to distinguish a Settler from a possible Oracle though (hint: Settlers have a higher increase in production than other builds because they get speed up by
) , and it's impossible to distinguish a beginning other Wonder from the Oracle. It still can be of help if i. e. seeing the one AI's capital that has Priesthood, and knowing that it hasn't started on something big, or if the
exceed the cost of Oracle, that it must be Mids, GLH or ToA.
A very simple formula for calculating the
an AIs city currently has stored in a build was found by the player
Doshin:
Doshin said:
Hammers = SabotageCost / InfluenceCivicsCost * 67 (Quick speed)
Hammers = SabotageCost / InfluenceCivicsCost * 150 (Epic speed)
Hammers = SabotageCost / InfluenceCivicsCost * 200 (Marathon speed)
(5000 / 800) * 200 = 1250/1500H
Addition: The modifier for normal speed is 100.
2nd addition: If you can't see the InfluenceCivicCosts, use the City Revolt Costs. Those are about 10% too high though, so for more accuracy, conduct 10% from them, before you divide the SabotageCost by them.
As the question is how bad it is to miss a Wonder by 1 turn though: That depends heavily. The only Wonders you'd really need to build yourself are Oracle, HGs and TM. Missing out the HGs in a Corporation game without a PHI-civ can be terrible though. Missing the TM is often the more common case on Deity, because AI gets mostly GEs during that time and simply 1T-builds it. Losing Kremlin is horrible too, because Kremlin is simply a game-changer, but that also really applies to competetive games. I won't judge every wonder in single now, because the truth is, that I don't build any of them regularly. Building the Mids i. e. is imo. worse than settling 3 cities instead of them. Parthenon and TGL obsolete so fast that they mostly don't matter in my games, especially as I also don't research Aesthetics myself, or only after Education
.
The list of
Pangaea is actually very good to show you, which Wonders are worth it at all, or under which circumstances. A 2nd wonder which would make me quite the game would btw. be the GLH on a watery map or the sixtine Chapel in a competetive Culture-game.
Remember that formula above, it's really simple. A devided by B or by C -10% and watch out for AI getting GEs. Should an AI ever get a GE and be able to build a Wonder you really "need" , think about gifting it more techs that unlock Wonders, so the chance gets divided. AI loves to GE-rush the Apostolic Palace i. e., how about gifting Theology to a civ having your religion or your neighbour that you plan to invade? ^^
Hth.
[EDIT]
Here is the source of the formula: Tachywaxon's Thread of Game Mechanics . On Deity and I believe also Immortal, the AI also gets an era modifier, so on Deity, the productioni of AIs in i. e. Industrial times is 5 times as high as it normally would be (guessed) but at the same time, all costs that AI got are further reduced by 5%. Accurate numbers in the thread (afaik) .
