Whipped/chopped Forges and CHs after MC. Boudica made peace with Biz but she DoW Biz again soon after the peace treaty ended. Got many failgold from Parthenon, Colossus, and Sistine. I lost my patience while waiting for the failgold from Sankore, so I finished it myself. AP was built by an unknown Hindu AI.
Pre-built WEs, generated some GMerchants to upgrade them. Also upgraded some highly promoted HAs. Built Taj Mahal. Attack with Cuirs. Only 1 or 2 turns after I DoW Boudica, she got dogpiled by Biz:
- or more exactly Biz took his revenge, as Boudica DoW him twice
Boudica capitulated on T215:
(note that Boudica had a city called "Hanover" - that was a city she had captured in her previous war with the Germans)
After capturing many cities from Boudica, the financial situation was close to -50

per turn even at 100%

. I was under Slavery, so it was impossible to generate a GMerchant under Caste

. To solve the economic problems, I decided to attack the nice dude up north, as capturing each city instantly gave 100 - 200

.
The nice dude built some shiny wonders for me
He also build Mids for me - what a nice guy
(the GGenerals settled in these cities indicated how many units Biz and Boudica threw onto each other

)
Welcome home, Notre Dame
Apart from so many shiny wonders, he even gave me 2 techs with capitulation. This dude was surely one of the nicest people
though he looked a little furious
I was wrong about the resources in my previous post. Our continent actually had Wheat but only in Biz' land. This trade was very important : finally the boulangerie could serve freshly baked baguette and croissant.
Sent caravels to find the three mysterious AIs. Met Justy who has 14 cities + a vassal Monty
It seemed Monty founded Judaism and Hinduism, but the wrong religion spread to SB. As a result, there were several wars on the other continent: Monty DoW Justy but ended up in Monty's capitulation, SB DoW Justy, later Justy DoW SB

. Monte had Shwedagon Paya and he was in Free religion.
After Astronomy, everyone except Boudica was under Mercantilism

. So I adopted Merc as well. Rep + Mercantilism, why not
The high

in the former Greek land was really good for getting GMerchants.
Didn't meet much resistance in my Cuirs attack, as Boudica and Biz had a decent number of units but they lost most of their stacks when they were busy killing each other.
The tech situation on T250. It seems SB goes straight for his favourite civic, Environmentalism before Rifling

.
Perhaps Rifles + Cannons would be a solid combo to attack Justy? Or Rifles + Arty? Maybe some Grens as well...? as Monty is very close to Rifling.
