This was a nice and peaceful turnset. I focused on teching to Astronomy and managing my economy, leaving Charlie to his own devices. He seems to have crashed his economy by expanding so much, but he will recover over time.
I deleted many of my units to save gold. I did keep the catapults and elephants, figuring that they would be useful in a future war. I built wealth in a lot of places and settled city #8 for the deer in the north. I got a great merchant and decided to use him for a trade mission. 1100 gold seemed like a good deal to me.
One mistake that I made was dawdling too long with getting out a great scientist. I had to avoid Code of Laws to keep the Astronomy bulb open, so my only option was to run two scientists somewhere for 34 turns, and I don't think I got that started quickly enough. In hindsight, I should clearly have avoided teching Meditation in the first place, that way the bulb path would have been keep intact even if I traded for Code of Laws.
Numerous great generals were born elsewhere in the world. I do think I will end up attacking someone other than Charlie, so it's good that the other AIs are fighting each other.
I ended up reaching Optics at 200 AD. Charlie was being stubborn and would not give me Calendar. Even after gifting him Monotheism, Horseback Riding, and getting to +10 relations he wasn't friendly. I decided to self-tech Calendar and he became friendly immediately after I finished it. (Of course.)
It was a pretty strange game. In the end I didn't even bulb Astronomy; I just teched it normally because the Great Scientist wasn't coming along fast enough. I should have it by 600 AD or so, not great and can definitely be improved. I think if I replayed this map I would avoid Meditation, focus harder on getting Charlie to friendly (maybe gift a city), and make a trade for Code of Laws. Maybe I would start a golden age and farm two great scientists in caste system.
I guess I should talk about Joao and Izzy, but there isn't much to say. They are semi-isolated judging from the espionage points, and they are best pals with their shared religion. But despite that they are completely backwards, barely even in the Classical era.
And that brings us to 600 AD and Astronomy. That date isn't very good of course, but I do think I can get to Steel pretty quickly from here. I think I will start up a golden age, switch into Bureau and Caste, and get out some great people. I could bulb Chemistry or get out great merchants to upgrade trebs to cannons. I think Isabella is a good war target here. If I take out their continent I could probably win a UN victory. Mansa Musa might build the UN.
