Been a busy week for me as well, but with a short rotation and everyone busy, I figured I could take a couple of days to play my turn.
I didn't do much, but I think I'm leaving the next leader in very good shape to make some progress.
(0) 350 AD - Heavy-handed vetoing all around.

I agreed with your comment about the aqueducts, hotrod. I looked at the cities building ducts, and most of them didn't have a marketplace, cathedral, or granary, and were at their happiness limit at size 6 due to war weariness. If we'd have built the aqueducts, we wouldn't be able to build anything else until we'd gotten those other three buildings done in each city, and it didn't seem wise to tie them all up for that long.
I realize that early/middle ages was can seriously stunt a civ's growth, especially when they don't let their cities grow past 6, but I didn't think we were ready. I swapped them to marketplaces, because they'd need those to grow anyways, plus they could provide some immediate help with the war weariness and the cash flow. Cities that got markets done got switched to units, but it should be no problem for the next leader to swap them back to infra if they prefer.
Also, we have 30 workers, so it was time for Tenoch to close the worker factory. I was thinking temple, then aqueduct, but plans change (see below).
I MM'ed all our stuck-at-6 cities for shields, with pretty good results (though we don't have a lot of high-shield tiles for them yet of course).
The Babs have education

They lack gunpowder, but Greece has it. Our library's days are numbered.
I rush a temple in Camulod. Even with saving gold for knights, we'll want to get some culture going down there.
BT - The Mongols attack our MDI, win, and capture the settler it was guarding! [punch] To add insult to injury, a Bab settler pair swoop out of the fog and settle right on the Alesia ruins. :die:
(1) 360 AD Oh well, this should be interesting, then. Tenochtitlan seems like the best choice for a new settler (we'll want to settle something close to Entremont, I'd guess). Our stack of units down south heads back to Camulod, so it will be ready when chivalry comes in.
Our incense deal is up. Last turn, Greece was offering to pay something for theology. This turn, theology won't even pay for the incense. So, I trade theology, 3 gpt, and 6 gold to Greece for incense. We no longer have to pay the Mongols for our ROP.
I wish we could import more lux, but there aren't any more.
(2) 370 AD - Teoti swaps to pikes for a while so that we have something to cover our beautiful longbows when they're ready for the long march south (hopefully there will still be a war by the time they get there).
BT - Babs now want some gpt for our wines for silks deal. The Greeks want us to ally vs. the Babs, no thanks. Chivalry in, science off.
(3) 380 AD - Our southern workers will need to help the Mongols with their road construction if we want resources to flow south.
We are the first to Chivalry, but I'm just not seeing any good deals. Greece still has a monopoly on gunpowder, which would be outrageously expensive, even with our monopoly on chivalry. The Babs have a monopoly on education, but I'm guessing we don't want to buy that (especially if we have no gunpowder yet). All civs will pay all their gold for chivalry, which isn't much. Greece has some 40-odd gpt, the rest have chump change. I decide to hold off, maybe something better will come along?
BT - Market completes in Tlatel.
(4) 390 AD - Seven knights are upgraded in Teoti. The road to Camulod will be done soon.
BT - Tenoch settler - temple
(5) 400 AD - Knights head south. There's also another stack of a pike, some longbows, and that settler. They'll arrive in 2050 sometime.
Still no change on the Chivalry front. Both Greece and the Babs are able to offer slightly more money for it each turn. I wait...
BT - Disease in Teoti.

The Celts move some units up towards Camulod.
(6) 410 AD - I use our 2 MDI to clear some Celtic MDI off the road to get our workers back home. One has to stay exposed while slightly wounded, but at this point it seems like the horses are more valuable, so I don't cover it.
BT - Greeks, Babs peace. If neither of them have chivalry, but they trade their current techs, we're in good shape. Disease, part two, of course. Tlacopan's market completes. Greeks complete Leo's. We need to do something about those pesky Greeks.
(7) 420 AD - Well, the borkering plan would have worked, except for one thing- it looks like the Mongols got Chivalry just this past turn, and that plus the peace caused everybody to trade everything. One more turn from the Mongols and it would have been a different story. Anyway, our library will expire next turn. Hopefully, the Mongols will still lack gunpowder when that one comes in (they have chivalry and education).
BT- Gunpowder and Education come through the library. It seems quick, but I always figure it's worked well if I manage to get gunpowder out of it. Oh, and we have saltpeter under Tlaxcala. [dance] . The Babs start Copernicus.
(8) 430 AD Hmm, the Mongols do lack gunpowder, but they're broke. Sigh.
BT - Babs request change and TM, cave. Tenochtitlan temple - market. BTW, our small cities with markets are doing just fine now, happiness-wise.
(9) 440 AD With the Babylonian wars over, the Greeks look to be focusing in on the Celts. They have a lot of units moving south, although we have the only knights I've seen so far. They look like they might be headed towards Veru. I'm thinking we might as well just head for Entremont to ensure that we get there before they do? The roads are clogged with Greek units and hard to use.
(10) 450 AD Mostly moving units, hopefully setting up our next leader. Who knows, the wall could fall this next turn!
Tear Down The Wall!
