Thanks for all of the tips! I did some of those things right, like ignoring Chemistry and Fertilizer. (I did use Chem as filler to help with a timing mess I got myself into, see below.)
I know that I made a few big mistakes in my game. For example: Because I planted too many scientists and timed my policies poorly, I had to faith-buy a late scientist to avoid wasting the Rationalism freebies on cheap tech, which didn't leave me enough faith for an engineer.
Speaking of Rationalism, do you try to finish it as late as possible, as soon as possible, or something in between? I tried to use it late and wound up in a bind where the next policy came too soon but the one after would be too late.
If you don't mind, I'd also like your opinion on the Great Library and bee lining Theology. I normally ignore the GL, but it's easy to get on Warlord, and very tempting to springboard the NC and start the Long Count by turn 62. But I'm concerned that I'm hurting my long-term growth by giving up Artemis and delaying water wheels. Still, Long Count is super useful for early admiral exploration and hurrying Petra, if you get it soon enough.
(In this game, I popped Writing from a hut on the turn I finished Pottery, so GL seemed like a mandate from the RNG.)
