Before:
IHT: I land the knights and 4 vet pikes on the hill. The rest of the pikes capture the two Aztec workers in the south or scattered around the knights. This is meant to distract the Aztec troops. The pike on flat land should be more appealing for them than knights with the same defense on a hill.
IT: The Aztecs kill the complete all pikes on the flat lands and hit one pike in the stack of knights. All knights are spared.
Turn 1 (1410 AD) With 51 knights we manage to kill 2 infantry, 3 rifles, a guerilla and 2 cavalry. We have three knights with movemement points left to defend the city.
The thanks of our people? Severe war weariness

Lux tax goes to 30%.
IT: The Aztecs don't attack the city at all

They do kill a number of knights though.
The Great Library gives us Monarchy, Theology, Printing Press, Education, Gunpowder, Banking, Astronomy, Chemistry, Democracy, Economics, Navigation, Physics, Metallurgy, Free Artistry, Theory of Gravity, Magnetism, Military Tradition, Steam Power, Nationalism, Medicine, Communism, Industrialization, Electricity, Scientific Method, Sanitation, Espionage, The Corporation, Refining, Steel, Atomic Theory, Combustion, Replaceable Parts, Flight, Mass Production, Electronics, Motorized Transport, Rocketry, Computers, Space Flight, Miniaturization, Ecology, Synthetic Fibers, Satellites, Ironclads, Fascism
It remains strange that we didn't get Music Theory and Amphibious War.
Turn 2 (1415 AD) The Ottomans are the only ones ahead of us in tech: Fission.
The good news: we have rubber. The bad: we lack the rest and there is no trade option (apart from saltpeter). Coal is close by though, in German Hareid near our core. Other coal is in the east, also in German lands. Aluminum and Oil are in the south, in Germans territory. No aliminum: no Apollo Project

I can get us coal by roading the 2nd German coal. Aliminum and Oil are not tradeable. But the Ottomans have more than one source of both. The Aztecs also have both (but don't know what Aluminum looks like).
War weariness shot to the highest level and the Aztecs won't talk. I push lux tax towards 50%. We have 25 knights left, but we are well within our upkeep limit. I give Teno to the Ottomans and the knights fly home.
I give the Vikings Ecology for Music Theory, Amphibious War, 450 gold and 63 gpt.
IT: Germany has lost a lot of troops. Only 15 units are running through our lands.
Turn 3 (1420 AD) I renew our two lux for one lux deal with the Ottomans. We pay an extra 11 gpt.
IT: Germany now comes with a lot more troops to take the Ottoman cities in the north. Tyre deposed to Germany. It is logical, but we had it for so long

The Aztecs have Teno back. Our first factory is in Persepolis.
Turn 4 (1425 AD) I can get no more than straight up peace with the Aztecs. They then give us Oil, Furs, Dyes and 2 gold for Atomic Theory. Lux tax back to 0%. We now make 381 gpt.
The price for iron are absurd: 100 gpt.
IT: Well, we connected the coal, but the Ottomans now take Larsa, so that won't help us
Turn 5 (1430 AD) Germany learned Nationalism. So now I have the liberty to sell them a useless tech, Fascism, for iron and gems. I waited until now because I didn't want to give them Steam or Nationalism.
Turn 6 (1435 AD) Not a lot to do. We obviously have not enough workers. It's really pathetic.
IT: Germany has Larsa back. Our Tyre probably will fall to the Ottomans.
Turn 7 (1440 AD)
The Ottomans land a SoD near Larsa. I will have a settler ready, since it is size 1.
Turn 8 (1445 AD)
IT: Hmm, size 1 Larsa is captured by the Ottomans, not razed

They DO raze another city to the east.
Turn 9 (1450 AD) A settler is ready to claim a spot near Larsa, but I fear that we won't get a decent place there, unless it is 2 tiles from Larsa and therefore considered by the Otto's as agresssive.
We can't trade Aluminum and coal is absurdly expensive. But with only 9 worker railroading would be difficult anyway. We have a lot of money and could steal Fission safely, but all civs are Fascists, which means veteran spies and less chance for us on success. War with Babylon (they also know it) and Ottomans means sure loss imho.
