Workers
13 cities, 8 workers - well you were too busy with military units spamming, which was more important for sure.
Indeed, there aren't that many Workers, but since we had a lot of them early on, they did their job well.
On the mainland, there are only a few squares left to improve, and just about all, if not all, of those unimproved squares currently has a Worker standing on them.
There are some Forests left to be chopped, but those were left intentionally, so that National Wonders could get built more quickly or so that they could be saved for a bit more production and future Lumbermills, as per the player's preference.
Shipping some Workers over to Montezuma's area can and should happen now, since we have control over a large enough chunk of land for the Workers to be safe.
Civics
My guess you did not adopt OR because few Confu cities you got are focused on units. Adopting theocracy then? You got it not long ago, so it could not help you much, may be worth it still.
A good guess. What you said is pretty much the reason for not switching into Organized Religion. While I love that Civic, I had no time to prioritize building Missionaries, and with only a few Cities having the same Religion and our tech pace already very slow, and with us building more Military Units than buildings (only buildings get the production boost, not Military Units), it seemed better to sacrifice that extra bit of production in favour of saving about 8 Gold per Turn in Civic Upkeep costs.
One unfortunate consequence of having so many Cities is that switching Civics will now cost 2 turns. With us about to learn Civil Service, and with the intent of allowing players to choose between Organized Religion and Theocracy, I decided to wait until we learned Civil Service so that both Civic switches could happen on the same turn--which will cost us 3 turns of anarchy, for a net savings of 1 turn. Plus, it means getting into Bureaucracy a bit sooner, due to the minimum 5-turns-between Civic switches rule.
Since Gilgamesh has been actively spreading Confucianism to us, and since we're already running that Religion, switching to a Religious Civic in a couple of turns does look like it will be an attractive option.
Exploration
The eastern continent was mapped out by a lone Galley and a lone Warrior.
We recently got some free Caravel exploration (before learning Compass or Optics) by buying a World Map, which shows us some of the eastern islands.
After a few turns, it would be worth it to buy World Maps, while NOT trading away our own World Maps. That way, we might get the Circumnavigation bonus without ever having to build a Caravel.
After that point, one could sell the World Maps if one doesnt mind this intelligence falling into the hands of the AIs--Gilgamesh will likely have sold much of the info on our starting area already anyway.
Tech Level
Tech could be worth, since advanced guys are at WFYBTA.
Yes, we avoided getting some cheap techs in trade, but of all of the AIs in our game, only Gilgamesh is not stingy on WFYABTA.
Technically, ALL of the other AIs in our game should be at the WFYABTA limit, but several of them have "forgotten" about earlier trades.
We have Gilgamesh at Friendly, which is great for avoiding being a war target, but it would actually be better to have a different AI at Friendly, so that we could avoid the WFYABTA limits. Gilgamesh has a very high WFYABTA threshhold, so we won't hit his limit for quite a long time.
Indeed, the tech level in my game is likely going to be behind most players' games. We're currently 2 turns away from getting Bureaucracy and we do have an Academy in our capital.
Religions
Pity hindu did not spread to you so you could deal with it. Diplomatically good though.
Yeah, we got Buddhism, which will help since it is the Apostolic Palace Religion, but we unfortunately got it in a City that will take a while to mature.
There is no real chance of getting Hinduism anywhere except via war or by founding a junk City and hoping that it will spread.
Gilgamesh-Bismarck War
Interesting how is Gilg-Bis war going. Gilg seems to have better land, while Bis is a better troop spammer.
It is a great thing that this war is pretty much being fought to a stand-still. It means that once we're done with Monte and have shuttled most of our troops back to the mainland, either one of those two AIs will still make for a juicy target to attack.
Los Angeles
Ahahaha, yeah that gifted City is causing a minor problem culturally. On the plus side, though, he built us a Work Boat!
So, if and when we do get Cultural control of the Fish, they'll be both improved for us (we have a Work Boat standing by for the other Fish).
It would probably make sense to build a Confucian Missionary on our mainland and ship it over to Los Angeles ASAP, to help us in winning that Cultural battle. We have two Cities that are running out of things to build so are building Confucian Temples to push back Gilga's Culture--they already have Confucian Monastaries so one or both of them could switch to building Confucian Missionaries immediately, without requiring the Organized Religion Civic.
