RBC16, 1500AD, The word is: Either continue to improve our Economy, or try to snatch the last gasping delayed twofer.
I will go along with option twofer, mainly because I cannot even remember when/if I ever played this way. At this stage it is usually deny the AI any techs/money what so ever by any means possible in my normal games. It will be refreshing for me
Too bad if you do not agree, because the buck was on me
So I fire up ye olde trading screen.
Korea would give us 10 gold and their world map for the secret of Steel. No thanks.
Hmm, Montezuma has 45 gpt and 60 gold, but wants Combustion, tempting, tempting. I need to check the other offers before deciding.
France is up Replaceable Parts, India is up Flight and RP,
Byzantine and Hannibal of the Carthaginians are up a lot, and should not be fed.
We can self research in 21 turns Atomic Theory.
We have 365 gpt income if we go full income, and steals looks like a promising pastime, but then we need be ready for one or more small wars.
Sorting our cities by shields is a depressing sight. We have one city doing more than 30 shields. We have three cities doing more than 10 shields !!!!.
Ooo, I missed one, Chinan makes 11 spt., o joy. I will keep Chinan in mind if I decide to try and rush a Stock market anywhere. It is building Cathederal now, and it is needed if we want the city to grow and earn money.
Having sold maps earlier, I manage to get Atomic Theory from China for 287 gpt and 3 gold.
Then I am sorely tempted to ask the Chinese to vacate our premises, but I will wait for one turn so I can get Flight first.
I feed the Aztecs Combustion. I can use the money better, and hopefully I can use Atomic Theory on them if they discover something interesting in the IBT.
IBT:
France wants 9 gpt for their Ivory now, and I fork up. Canterbury Rifle->Rifle,
1505AD I fortify the pollution crew, and hope you will remember to unfortify it if I forget to do it when my turns end. Worker action is heave with the remaining three workers
Get Flight for Atomic Theory along with 100 gold and 3 gpt, and thats Full price for India. Hope the French can pay me more, as I had hoped to regain most of the money paid for it.
The Chinese is putting a lot of pressure on Korea, and Korea is not expected to live long.
I rush the galleon in Warwick in case we would feel like poaching a bit.
There are some cities that even with 50% corruption would be high shield cities in our lands.
I instantly regret rushing the galleon, as I do not have any settlers, and I really should save up for a Stock market and 1000 gold.
I pause for a couple of hours here, while I wait on the verdict of my rules question.
IBT: Cirta complete Factory, and I start Bank. This size 3 city is our fourth best shield producer.
Warwick completes Galleon, and start another.
I get really nervous as Byzantines start Internet
1510 I get Coal and Replaceable Parts from France for Atomic Theory. Guess how much rubber we have
Yup, right we have none.
Closest Rubber is in Korea, but we would need to confiscate it to get our hands on it. On the world market, there are no rubber available at any price.
IBT: France comes up and offers Communism for Flight and some spare change. I make the deal. This could have broken the rule, but I am fairly certain not the spirit of the rule, as it was a deal the AI offered up.
Nottingham Guerilla->Ironclad,
1515 Nothing of any notice. Becoming more and more convinced I should rush a Stock market in Chinan, so we can start the Wall Street.
IBT: Intelligence agency complete. And I switch tiles for max food and start Artillery. There was no way for me to reach 70 spt, in which case I might have built Riflemen or Flaks.
1520 I partial rush the Stock market in Chinan by way of Cathedral.
India just got Mass Production. We can get 16 gpt from Aztecs for replaceable Parts, but I will wait unless I get close on trying to get Electronics. Electronics was expensive, so it better wait until we can steal it.
Best research I can get is 46 turns at 130 gpt cost.
IBT: Canterbury Guerilla->Guerilla, Saldae Barracks->Rifleman,
1525 Clean Pollution, twiddle cities, press next turn.
IBT Aztecs have managed to sign peace with most of the world. London Artillery->Galleon,Nottingham Clad->Guerilla, Cadiz Courthouse->Cathedral, We find a new source of Oil 
1530 Nada.
IBT: Aztecs and India sign MPP, London Galleon->Destroyer,
Aztecs declare on France, Carthage start Seti,
1535 Look for trade opportunities, and find only one. Get Mass Production from India for Our oil.
IBT: Canterbury Guerilla->Commercial Dock, Chinan Stock Exchange->Dock,
1540 Keep looking at the trade screen, hoping France will get Electronics. Nothing to show excepct a few coins for our new maps. ( I have been foresting/railing now while we have coal. )
IBT: London Dock->Wall Street Errrrr, I am missing a Stock Market somewhere, since I cannot build Wall Street. I build a battleship instead. Russaddir Library->Dock
1545 I rush the Bank in Hastings.
IBT: As if things are not bad enough, Byzans and Cartage sign an MPP. So much for getting them to fight one another.
Hasting Bank->Stock Exchange, Get an embarrassing civil disorder in Cadiz for some reason I missed the growth.
1550 Move our workers. Nothing visible on the trade board.
I think we are in deep trouble, and we need to stop Carthage and Byzantines in their tracks if we want to launch before they do.
However to manage that we will want access to rubber, and easiest way to get that would be to grab the Aztecs source.
