Sul 5a from 870 AD
870 AD (0):Change Warwick from colosseum to Cathedral, adds 6 turns but I think a better value. Mines at start and finish at Norwich. Hurry temple for a quick culture fix at Hloban for 76 gold. Change Oxford from knight to cathedral, no barracks is in the city and with Sun 14 turns away a regular knight would be finished in 8, decided to wait. Upgrade spear to pike in Nottingham, London and York. Change York from Knight to pikeman. Many cities are only defended by warriors of not at all, will start building defensive pikes after the last of the knights complete. Would waste to many shields to switch them now. Increase research to 50%, invention in 3 with +25 gtp.
Establish the following embassies: Iroquois 54 gold, Russia 59 gold, Egypt 62 gold, Aztecs 74 gold. Iroquios are 66 turns from SunTzu. Egypt 54.
880 AD (1): York builds pike orders up another. Hlobane finishes temple start courthouse. Hurry courthouse in Leed for 92 gold, wont held with production yet but gold will get a boost.
890 AD (2): Sell maps for much cash, Iroquois pay 50 gold, Egypt, 6 gpt and 40 gold, Zulus 30 gold. Monty, Cleo, and Cathy all have Monotheism. No other trades. Canterbury and NOttingham finish knights and start on pikemen. Newcastle starts cathedral. Leeds finishs courthouse starts library. Change a few roman cities to courthouses and rush in Rome for 224 gold. Cumae for 196 gold. Will evaluate again to see if the rush was worth it. Begin moving settlers south to join a few cities not sure which ones yet. Reduced science to 40% and get invention in 1 with +70 gold. Upgrade spear in Cantebury. Hurry temple in Norwich for 64 gold.
900 AD (3): Learn invention and start on guns, due in 6 with +24 gold at 50%. Join settler into Nottingham. Disease strikes Leeds. Hurry Warwick catherdral for 176 gold. Cumae completes courthouse start temple, Rome ditto. York pike and starts another.
910 AD (4): Disease round 2 in Leeds. Some more worker movement, Warwick completes catherdral and starts catapult, Nowich changed to courthouse, fire entertainer. Guns due in 5 with +24 gold.
920 AD (5): York builds pike and start another. Ditto for Nottingham and Canterbury. Liverpool finishes aqueduct and starts harbor. Disease hits Leeds again

. Settler joins canterbury. Some pike movement North and south. I realize now that gunmen are just around the corner but I think defence of these cities couldn't wait.
930 AD (6): Settler 3 joins Hastings. Pikes move again, disease at leeds again. Sunzu due in 8. I think we have a good shot at getting both.
940 AD (7): York builds pike and starts Leo's. Due in 30 turns. I don't think the others will even get there with the cascade. More worker movement.
950 AD (8): Reduce science to 20%, guns due next turn with +154 gold. More pikemovement, and worker actions.
960 AD (9): Guns researched We have 2 sources of Saltpeter hooked up and another by Canterbury. start on Education due in 5 turns at 50% with +22 gold.
970 AD (10): Upgrade 7 pikeman for 420 gold. Canterbury switched to musket.
We have 679 gold even after my spending spree. Upgrades, rush buys etc.

.
Started Leo's at York, Sun is due in 4 turns. We are way ahead in tech, not a surprise, haven't sold contact to Zulu or Persia, Don't.
Diplo check: Persia lacks Engineering and all that follow, and Theo. and iron

. Has only 7 gold and Monarchy
Zulu: Lacks Engineering, Theo and Chivalry. has 25 gold. He too lacks iron.
Iroquios: Have engineering but not theo, chivalry, or invention. has only 3 gold.
Russia: has theo and engineering but lacks chivalry and invention only 4 gold.
Egypt: Lacks invention, and chivalry, needs iron and horses and has 38 gold.
Okay, I spent a lot of money on improvements, upgrades, embassies and we still have 685 gold and +24 gold per turn. SunZu is due in 4 turns, 3 if you run low on food. Zulu and Persia don't have iron so no immortals or knights or pikemen. There are still a SOD by Leeds, I focused on defensive units but a war with Zulus would not be out of the question soonish. With the few courthouses I rushed it seemed to improve the production of those cities, recommend buying some more. Melding the settlers seemed to work out too.
