Have you given up on Lightbulbing Theology? Because we'll need to self-tech Meditation in order to do so.
Also, so where in our build order do you want us to slot in the Hindu Missionary from the Capitol?
Because in order for Alphabet to be of use now, we'll likely need Zara to be Friendly with us.
We'll want him to share a religion with us, and we'll want that religion to be one that the capitol can run.
An alternative would be to build TWO Missionaries of another Religion and send one to Zara and the other to our capitol. Confucianism (if we get it) could give us one of those Missionaries, but then we'd have to build a Missionary immediately in the Size 1 city that founded the religion.
Yes, he knows at least one other AI, so that might help, but only if that other AI knows the same tech--otherwise, Zara still won't give it to us unless we are Friendly with Zara.
Trading with a Non-friendly Zara
I ran some tests. If Zara knows no other AIs, he will only trade a couple of "basic" techs--Fishing and Animal Husbandry.
If Zara knows one other AI, he will trade the same "basic" techs but won't trade us any additional techs unless that other AI also knows the tech.
If Zara manages to meet two other AIs, he will trade us the same "basic" techs but won't trade us any additional techs unless one of those other AIs also knows that tech. A weird exception was Math: Zara knows Shaka and Gilgamesh and Shaka has Math, however, Zara is still holding onto Math.
It seems that somewhere in BUFFY or BTS, they took out (accidentally?) the message that lets you determine if an AI is holding onto a tech because they want to build its corresponding Wonder. These days (for whatever reason), you don't get to hear about when an AI is denying you a tech due to them wanting to build the corresponding Wonder.
Perhaps Zara just likes the Hanging Gardens and won't trade away that tech for said reason. Perhaps he has another reason, like fearing that we'll beeline Construction after learning it.
After creating the saved game, I added Writing and Math to Gilgamesh's tech repertoire. All of a sudden, Zara will trade Math to us again. So, it seems that Zara treats Math as a very important tech that he won't trade around easily. That's probably the 1 tech that we REALLY wanted to get by beelining Alphabet instead of Mathematics, and HE WON'T GIVE IT TO US!
Regardless of the reason, according to my test game, unless Zara knows Math AND the other AIs that he has met also know Math,
we will not be able to trade for Math from Zara unless he is at Friendly (and he happens to also conveniently research it for us).
I'll attach the test game. Here are some details about the test game:
- We only know Zara
- Zara knows Shaka and Gilgamesh
- I have no idea if Shaka or Gilgamesh know any of the other AIs--this point shouldn't matter, anyway
- The techs that Zara knows which we do not know are easy enough to see when you look at the trading screen
- I gave Mysticism and Meditation to Gilgamesh
- I gave Writing and Mathematics to Shaka
Setting up your own test game
Perhaps someone else can run a separate test game to validate or contradict my results.
Note that to have an AI "meet" another AI, I generated a map where we'd be isolated on a continent with Zara. Then, I would World-build in a Scout from a different AI and place it next to Zara's cultural borders. After ending the turn, the two AI would "meet" each other. Then, I deleted the other AI's Scout using the World-builder (this last step was probably not a necessary step, but it was a fun one!).
