First off, I launched the GAge as advertised with the GA from winning the Music race (that I thought was lost, so thanks for putting me straight so I tried!). Changed things slightly in St. Petersburg. Ran 7 scientists there too, at -6

per turn. With that for two turns, and 6 for 1 turns, we got him in 3 turns instead of 4, with 2

to spare

The city lost a fair whack of the foodbin ofc, but I wanted the GS a bit sooner for the Edu bulb, and the city has food to burn in oodles anyway.
Like Fish Man said above, I too like to check the trade screen to try to figure out what the AIs are teching, especially at crucial moments like this. One turn in, and it becomes clear he is teching Civil Service. Good!
Wang's doing a lousy job roading the path for my GM, but he brings a settler party. Saladin beats him to everything though. Not sure where that group went eventually, but he really should have settled the jungled rice and ivory. Maybe he wanted to get up to my horse or something.
Only two turns in, but here is an overview shot from 1AD. In a golden age so the numbers are boosted of course, but 356

is quite nice, without an academy. I forgot to check, but if BiC's numbers from before were correct, we had maybe 280 without the GAge.
Next turn I bulb Education for slightly over 1700

, then one-turn the rest of it.
Meanwhile, Mansa's capital Timbuktu is under siege by Gilgamesh, but he's not going to get through that I don't think. Even with a bunch of catas, 4-5 longbows is rough for 6-strength units.
Not long after they peace out. I think Gilgamesh attacked first, but many of his units survived. Not entirely sure what occurred, but at least the war ended.
Not very interesting, but Wang cancelled a deal. Fish for Dye or something like that. So I cancelled the Horses deal and re-negotiated. Not bad
T120 and the next GS is out from Heliopolis, again with 2 spare

. I wait one turn to pop him due to 3-4 cities growing (also needed Compass). Then check what Mansa may be up to.
Yeah, he ain't teching Education yet. I'm going for it. Teching through Nationalism is 8-9 turns (without GAge boost), but I feel it's doable. There is still the GM that will soon arrive at the Artemis city. What will he fetch?
Very nice! That will last a while
Also trade Machinery+100g from Wang in exchange for CS+Compass. Once Mansa gets Engineering, there was a one-turn window of getting it. I didn't, but probably should have. He then started on Notre Dame and locked me out, but giving him Education at that point would have been safe.
Mansa winds up building the AP btw, which then becomes Jewish. Darn shame. I have zero cities infected with it, so no free hammers from our cheap temples. Would have been nice. Isabella really ought to have secured that, but started it too slow. She ended up with a lump of 340g (it may have been a different wonder, I don't recall), and we got 310g of it for a tech she was reseraching (Music I think). Everybody had Philo at this point, except Saladin. He's likely to be my first target, but I trade him Philo for Theo+150g. More gold is always nice.
With that, we're at 375AD and we win the probably 1-man race to Liberalism:
Same turn Engineering becomes available again, this time from Gilgamesh. Diplo is a bit yucky here, but I'll just have to take the hits from worst enemies. I'm feeling pretty safe anyway, probably as the tech leader. Gilga lacked a few things most others had, so I have no qualms giving him Paper+Music+Compass for Engineering+70g. As an aside, Isabella was the first to Optics. If she is sensible she sends out several caravels to explore the oceans, because given the vast, vast amount of 'blackness' on the minimap, I have to assume there are islands or continents to settle.
Thebes isn't as big as in BiC's game, and I essentially halted growth here at 16, in favour of working more mines. It has also lost out on the wet corn for almost the entire game, which naturally prevents some growth potential. 16 is still a nice size, though, and it can now work all the cottages plus two mines. I'm short on health anyway, so growing more isn't that lucrative.
I took some overview shots too, but to fit in the save I can't include them here due to the 10-attachment limit. I've settled the island to the far east, which turned out the be rather good with fish+clams. Both were in the outer ring, so I don't have access to them for a couple more turns. A workboat is waiting, and another is being produced. Also settled near the iron where I razed a Russian city ages ago. Oddly enough the crab near our capital hasn't been settled yet, and it feels kinda pointless now when it can't work any tiles anyway. Admittedly another crab would be nice, but that's about it.
I have also built some missionaries because Isabella got a bad habit of sending them to Arabia. Looks like her two in our land now may be going for my own cities, but they may also just be going through to some new city here or there in Arabia or Korea or something. I've got a couple guys myself, so will see what happens.
