Where's Yamps? kcd, do you have time to play? If not, I can write up a PPP tonight to get the show moving again.
That would be best, no time for me these days for anything.
Some comments:
- We are already in the Liberalism race mode. Mansa/Shaka have CoL, Aesthetics and Philosophy, they are researching fast.
- Asoka/Ragnar are most likely not after us. Still, we should fortify our border copper city. Other AI could go into war mode as well. We don't have to switch to Slavery in that case, we could just keep the border with no offensive fighting.
- More workers are needed , to build farms and mines if we have to switch to production mode. We also have to build roads to connect our border city.
- We have to choose between specialists and hammer tiles and at this point in the game, I suggest we go with specialists for fast research.
- The alternative to Bure next is Calendar. However, we are food limited and not happy limited. Also, we can hire scientists instead of working plantations, gpp is worth more anyway.
- Race to Music we could lose, Great Library too. We'd gain more with earlier farms anyway so again Bure wins. We'll need the National Epic though soonish.
The remaining question is should we switch to Caste immediately or should we wait for Caste + Bure? Iiirc, we could get Bure in ~10 turns with more specialists. This is a matter of some calculation to see what's best. Since we're building HG, it might be better to wait a bit. In this case, we should build wealth in cities working the mines instead of caste specialists to compensate. There's also a factor of delayed great people to consider.

We shouldn't bulb Philosophy, at least not right now. Tao is gone and we don't have a religion to run Pacifism.
I'd say there's a very good chance that we'll need paratroopers. Oz has to be isolated from other AI and those mountains are a strong indication for this assumption.
@xcal
No war techs right now, we should tech fast. In case of a war, let's just hold our position. Btw, let's not forget about Monarchy when trade is considered. AI will trade that to us when we reach Priesthood. Feudalism as well will be useful for us later on.
Copper city should be fortifed more, archer has to stay there.
Our galley is useful for spawn busting where it is now. You'll notice the go-to orders for our archer in England to help with that. Barb city is spawn busting too btw. We all remember barb galley assults from previos games, but that was from pre-build cities. I suggest we bring back that galley later on to protect our sea food. Also, barb galleys won't see our unit if we keep it out of their 8 tile detection range.
I do agree however that we have to explore more, we should build more units to do that.
If we switch our EP to other AI, they will increase their rate against us as well.
I don't think we should settle much more, it won't help our research. The sooner we get a decisive military advantage to conquer more or all AI, the better.
