Okay, played four more turns, and now Aesthetics is in.
T71: Terrace is in in Machu. Assign the floodplain cottage over for growth. Tiwanaku grows to size 2. Bismark's settler heads west instead of north.
T72: Send our settler to Horsey city and build a 1 turn Quechua.
T73: Pyramids BIADL. Bismark settles Essen. Start barracks in Cuzco to get cover Quechuas for taking the barb city.
T74: Huh... look at this... Hatty's trying to take our city! I'll just stick some opportunistic kill stealers in place.
T75: And now only one archer left in Chehalis. But our odds are only 26%, so I don't. Settle Ollantaytambo and work the plains forest hill to get the terrace out.
T77: Aesthetics is in. Pause for input.
Culture:
Southeast:
Northwest:
I'm not confident in my choices so far. Sending both workers to get the copper out, and the barracks in Cuzco. We only need one spawnbuster in the south now, which is George at the moment... not the best choice as there are no convenient forested hills, but the combat 2 Quechua is in Olly's cultural borders healing to go and hang out the barb city in case there's a kill steal opportunity. There's a Quechua headed back from the northwest who can do spawnbusting in the south, freeing up George to be a scout.
Anyway... Aesthetics is in and I think we need trades now more than Great Library later, especially when we need every hammer we can get for workers, settlers, and units. So I've stopped here.
Bonus... Buddhist missionary headed to Cuzco!
