Summary
Quite a mix of MM, building, trading, and trying to fight a war that I hadn't really prepared properly for.
- We have 53 cities plus a settler in place, including a couple of towns we've taken away from the Mongols, and we have 11% of the territory.
- We know how to make Gunpowder but we have no saltpeter yet.
- Japan is at war with almost everyone.
- We are at war with the Mongols.
Turn 140 50 AD Preflight
F1: MM various towns. Starve Tsingtao (resisting)
F4: Our WM is out of date by about 30 gold. Trade round make 79 gold. Trade dyes and spices to France for 24gpt.
We have 141 gold + 153gpt. We could research Gunpowder in 9 turns, but it's probably cheaper to save up and buy it.
F3: We are rated average or strong against all civs. There are barbs reported near Chinan - probably on the islands in the fog.
IBT Carthage settler seen heading north for spaces. England declares on Japan. Jananese galley heads west on our north coast.
Beijing, Kiafeng temple->settler. Xinjian, Monguntiacum worker->settler. Camulodonum, Eboracum knight->knight
Turn 141 70 AD Move Euroswords south, knight west, workers to work.
IBT Babylon declares on Japan. We have a major dogpile on Japan! Japansese galley turns back east.
Shanghai riots as it grew last turn and is suffering from whip unhappiness. Mohacs knight->knight. Chinan worker->temple, Axima warrior->temple
Turn 142 90 AD 454 gold + 164gpt
IBT Tsingtao resistance ends. Tsingtao worker->barracks. Richborough, Curovernum settler->settler. Augustodorum knight->knight. Chengdu worker->barracks. ningpo worker->worker.
Paris completes Leonardo's, starts JS Bach.
Turn 143 110 AD Our borders have now enclosed the furs. Cut lux tax to zero.
France has Music Theory, of course. So does everyone else except Japan, who's at war with them all. We have a 2-fer opportunity. Buy Music Theory from Vikings for 513+WM. Buy Gunpowder from Japan for Music+WM+33gpt+7. Back to Vikings and sell Gunpowder for WM+513 gold. We have no saltpeter. France has one spare, would charge 20gpt+cash for it. Japan has 2 saltpeter, only one source hooked up near Kyoto. India has it connected at Lahore, but it's not linked to Delhi yet. Can't see any in Mongolia, but there's plenty in the northern hemisphere.
Sell WM around for a few shekels. France is ahead Banking. We are ahead of Babylon and Mongols by Music and Gunpowder, and China by Gunpowder.
Our euroswords seem to have reached the Mongolian border. Might as well keep going

After action report
There's a settler on a radius 5.x spot north east of Beijing, ready to settle there next turn. That completes the 5 ring for Beijing, having moved Nanking.
The war against the Mongols is in that stage where they've counter-attacked and we've lost several units. We're waiting for reinforcements, and hoping that the Mongols don't come up with too many more offensive units. I should probably have waited for the knights to get there before engaging them with the swords, but the Khorchin are doing a lot of damage to our knights as well. The hill towns defended with pikes could be taken with swords, but knights will be more efficient. It's probably better to use the swords as second string now, mopping up strays, and build up an attack with knights.
I don't know what stage of Golden Age they are in, if any. They've been at war with other civs before we declared, but I don't know if their UUs saw any action. They would give us three dead end towns for peace now, and we haven't really started to hurt them yet.
Banking is out there in three civs. I don't see it as important yet. We need Chemistry/Metallurgy/Mil Tradition, but the AI were fiddling with Music and now, probably, Democracy, Economics and Artistic Impression.
We have 130+ gpt, and 1500 gold in the bank. We have four luxuries, and we need some markets in our core cities to maximise cash.
MM is getting tedious, and complex with our tight build round the FP. I added one town near Ratae, and there's room for two or three more in the south. Several new towns filled in between the two cores, among the mountains, and there are several spots near to the Mongolian lands to be settled once we secure the area.
Have fun Tomoyo.
