Inherited Turn - Since CKS and I were ok with trading Metallurgy, and I was convinced it would do wonders for our economy, I pulled the triger. First thing to do was figure out what civ was the leader and therefore had the money... Ah, it's China. They have a zillion GPT (more than full price for Metalurgy!). No one else has more than chump change... That's not ideal, it just means we'll have to do this in a slightly different way.
Metalurgy to China for Astronomy and 255gpt. And now they mystery question is answered. Only China and Persia have Physics. So it's down to if I can make a deal with Persia for it. It does cost us a bit of cash, and I ordinarily wouldn't do this, but we don't want to trade our next tech, and we'll need Physics to select the tech we want to research after Cavs, so... Metalurgy, 36gpt and 12g to Persia for Physics. Astronomy and 86g to Zulu for Banking. Monotheism to Argentina for Dyes and 9gpt. Because they had some cash, not because I wanted the tech, Physics to Songhai for Incense, Music Theory, 29gpt, and 6g.
Luxuries off, Science to 100%. Mil Trad now says 8 turns, because the scientists are working... I go to a tundra village, hire one geek back, and viola, 7 turns
Looks like we have about 8 towns without defenders. Not as many as I was expecting. Change Athens to Musket, but leave Sparta on Knight so as not to waste a bunch of shields.
IT -
Thermopolae: Musket -> Musket
Rostov: Temple -> Barracks
1) 1060 -
IT - Beijing completes Copernicus. Not the civ we'd have preferred to get more science.
2) 1070AD -
IT -
Beijing: Musket -> Musket
Berlin: Courthouse -> Market
Sparta: Knight -> Knight
Konigsburg: Musket -> Musket
Delphi: Cannon -> Cannon
Egypt starts Magellans.
3) 1080 - The top 4 now have Navigation.
IT -
Hamburg: Musket -> Knight
Cornith: Musket -> Knight
Pharsalos: Musket -> Musket
4) 1090 -
IT -
Tours: University -> Barracks
Hanover: Harbor -> Cannon
5) 1100 Physics to Sioux for Navigation (so we can trade WM), WM, and 1g. TM to Australia for WM. TM to Zulu for WM and 65g. TM to Venezuela for WM, 38g, and 6gpt. WM to Songhai for WM. 209g, and 4gpt, TM to India for WM, 3g, and 9gpt. to China for WM, 118g and 9gpt
IT
Athens: Musket -> Worker
St. Pete: Musket -> Cannon
Sparta: Knight -> Knight
Thermopolae: Musket -> Knight
Chartres: Barracks -> Duct
Knosos: Cathedral -> Knight
6) 1110- Collect about 200g and 20gpt doing map trades. I did more of this later in the set too, but just didn't note it.
IT - We learn Military Tradition, and set sail for Magnetism, due in 8. It's a faint recollection that the AI prefers to research ToG over Magnetism, probably because it has an associated wonder. Not that it seems absolute, just a feeling... If right, by the time we get Magnetism,, we can likely trade with someone for ToG. Our people want to build the Military Academy... which I've neglected to prebuild?!

I read Greebley's thing and said to myself "of course I'm going to prebuild that, then proceeded to not do it... No excuses, sorry guys.
Athens: Worker -> Cavalry
Delphi: Cannon -> Cannon
Smolensk: Library -> walls
Sioux start Smiths.
7) 1120 - Several People now have Ecconomics. Lets hope they build Smiths on our side of the pond. Upgrade almost all of the non elite/non army filling knights to cavs. Per Greebley's suggestion, I do not upgrade trebs to cannons (which I've always wondered about anyway. Seemed a lot of expense for the benefit. Good to know going forward)
IT -Australia wants to trade WM. No reason to do that, so no.
Novgorod: University => Temple
Stutgart: Library => Courthouse (might be too corrupt to bother with it?)
Dijon: Library -> Courthouse (see above)
8) 1130 - Upgrade the last few non elite Knights (that I can find at least) Not sure what to do with the other 1200g. Maybe upgrade a few hoplites? I'll let the next player decide.
IT -
Lyons: Musket -> Musket
Konigsburg: Musket -> Temple
Cornith: Cavalry -> Cavalry
Yaroslavl': Courthouse -> Library
Avignon: Library -> Courthouse
Argos: Market -> Cavalry
Rhoades: Library -> Courthouse
9) 1140 -
IT - Rostov: Barracks -> Musket
Tours: Barracks -> Market
Pharsalos: Musket -> University
Orenburg: Cannon -> Cannon
10) 1150 -
Notes: Feel free to start the war any time. Hopefully the troops are not too far from where you want them. I kind of just added to the stacks Lee had already made along the boarders. Economically, we're doing great. We're down only Economics, but we're up Military Tradition. We'll have Magnetism in 5, hopefully first, and can trade for ToG and enter the next era if the AI has learned ToG by then. We should have plenty of cash and happy for the next set. After that... well, hopefully we can get rich with our free next era tech if needed.
I do feel the trades I made were fully justified. We went from break even, happy trouble, MT in 16 to getting 3 required techs, one of which we'd have had to research after MT, plus navigation and could research MT and Magnetisim in 17 total. I think we might have added one civ to the list of people with cavs when we fight them, and that sucks, but it was worth the tradeoff imo.
