The map got me. Having so few cities having been squeezed through a neck in the map by the Greeks and taking 10 turns to hook up coal just doesn't work.
Likely I'll play it out, but at Industrial Age I pulled Industrialization (good), but couldn't get the Corporation below 6 turns (very bad), Electricity below 7 turns (horrible), and Scientific Method below 5 turns (even worse). That's all of the 6 turns I could use up and still beat
@bluejay, and you can see where it's going. Refining 6 turns, Steel 5 turns, they add up.
I think I might be able to turn in another 690 finish if I want to turn it in at all. Can only turn in 2 games per update / board, so I might just hold it and see if my next attempt is better.
Interesting that I could even approach 690 with so few cities. I think my hot start (20 cities by 900 BC) with the Mysticism SGL was good, plus the early Medieval Golden Age to boost that period and get libraries and universities built. But in my first 690 game, I finished with over 90 cities and still was struggling for 4 turning. I also had to pack my Cap and my Colossus/Cope/Newton city close, which wasn't optimal.
With a decent map that allowed me to settle 60-70 cities by the Industrial Age, I think I could have gotten a 500's finish here with the Mysticism SGL.
Note - I've gotten 1 CB SGL (when I was on an island), but I think the AI are just popping it too frequently.
