I post what I finish...
We are a Republic and I didn't go for the Hanging Gardens. I choose to go for Sun Tzu. With that, we will be entering the Golden Age. Should we not get Sun Tzu, then Leo will do the same for us.
IHT: I rush-build libraries in Hastings and Stuttgart. Those cities lose one population.
IT: Currency comes in, we are in the Middle Ages. Monotheism is our free tech

Massive uprising of barbarians. Obviously we are not the first to enter the middle ages.
Hastings, Stuttgart, Hannover: libary->marketplace.
Turn 1 (10 AD) Colosseums switched to marketplaces. Greece got Engineering as their free tech. Russia isn't in the Middle Ages yet. I give them Currency for world map and 3 gold. Their free tech is Feudalism. Now we only have to wait for Feudalism to come in from the Great Library. I will then switch the Palace to Sun Tzu.
I cross the river to avoid having to cross the river with our Stack of Doom (SoD) near York.
Luxury has to go to 10%, because Berlin grew to size 7.
IT: Canterbury: linary->horseman
Turn 2 (30 AD) The free techs are traded around as planned

Next turn we can start with Sun Tzu.
-Elite horseman kills regular spear in York
-Vet horse retreats from regular unwounded spear
-Vet horse killed by regular spear
-Vet horse retreats from regular spear
-Vet horse kills wounded regular spear
IT: Aztecs near York with three swords. Monarchy and Feudalism come in from TGL. 22 barb horsemen near London. We have 1500 gold, but we may lose a lot because we can't stop them

Königsberg: aqau->market.
Turn 3 (50 AD) Leipzig switched to Sun Tzu. That will still take 20 turns
-Vet horse is killed by regular spear in Coventry
-Vet horse razes Coventry
-Wounded vet horse re-lines last defending spear of York
-Wounded elite horse takes York with 3 slaves.
I don't want to bother with the Aztecs, they are too far away now. We get 25 gold for peace.
The AI hasn't got the money to pay for Monotheism.
I decide to go into anarchy at the end of this turn. We draw 5 turns of them.
IT: Nothing much
Turn 4 (70 AD) Troop movment towards Warwick, Englands last city.
IT: 14 barb horses decide to attack a military stack of the Chinese. They are all killed

8 barb horses progress towards London. The Chinese stack is reduced to a warrior and a settler. America starts Sun Tzu.
Turn 5 (90 AD)
IT: The barbs move further and pass London.
Turn 6 (110 AD) One barb is killed by a vet horse.
Turn 7 (130 AD) 4 barbs are killed, two are left.
IT: One barb horse is killed, the other manages to kill one of our horses. But it is clear now that no city will be victim of them and that we will keep the money. America finishes the Hanging ardens. They were the only ones working on it, so we should be going strong with Sun Tzu.
Turn 8 (150 AD) We are a Republic now. Luxuries go to 20%. We make 54 gpt. Sun Tzu is in 18.
Aztecs give us 116 gold for Monarchy
Russia wants to pay 15 gpt for Monotheism. Doesn't sound like enough to me.
Embassy with Russia costs 53 gold
Embassy with America is 103 gold. I want to see how their Sun Tzu build goes. For 134 gold I notice that America still needs 29 turns.
America and Greece ar at war.
IT: Bergen: market->horse.
Turn 9 (170 AD) Two vet horses manage to destroy Enlgands last town, Warwick. But there's a settler around. Two other horses spot it to the west, with a spear. Elite horse kills wnadering warior.
IT: English settler walks back, to certain death
Turn 10 (190 AD) Our elite horse attacks the English spear/settler combo and kills the English.
The only civ with a tech over is is Greece, who have Engineering. We are at least two techs over the rest of them. No-one has Republic yet, as predicted by me
I agree that without a variant this game is won.
190 AD save
