Cam, if you could get an updated version of the PPP, we all, and I for sure, will be most appreciative! I am learning a lot from you![]()
Like how to mess up a Theology slingshot?!

I'm pleased that you feel that you're learning.
Revised PPP (as I understand it):
Edirne: The sole purpose of this city from now until 600AD-ish is to run those Priests and pop Great Prophets. Its build should continue to get that Jewish Temple up, and then run the first Priest asap. When the Buddhist Missionary (in a perfect world) spreads Buddhism into Edirne, we have to chop out that Buddhist Temple as best we can with the three available Forests (and then build it 'au naturale' from there) and run that second Priest asap. The north-north-west riverside Grassland in the BFC also to get farmed, but this city will be running a food deficit to feed the second Priest. If we can all 'micro' the builds so that we put as much food into the food box as possible while not slowing down the Temple builds, that'd work in our favour.
Ankara: Work the riverside Grassland to get the population up to 2, then whip out the Missionary. Send to Edirne. Possibly run a second Missionary build in case the first fails. Consider a Library for the culture.
Karakorum: Worker > Monument > open to ideas (?)
Beshbalik: Open to ideas ... maybe Forge? Maybe units in light of Barracks?
Istanbul: Library. Be careful about running Scientists not to interfere with Edirne Priests > Great Prophets. When Tufan comes out of revolt, we'll get its Marble. Therefore consider The Parthenon in Istanbul (around 20 turns) to assist with the final turns of the Great Prophet popping. Much less preferably in my view, but a Settler for the jungle-Gems to the east of Istanbul might be a consideration. Try where possible to work Cottages in addition to the Ivory, despite the pressure of the Library and Parthenon builds.
War: Take Tufan ... consider peace afterwards ... alternately re-group and head west for more warfare. Refer FiveRings's comment in post #140.
Technology: Complete Theology and Monarchy. If multiple trades for Metal Casting are available (Alphabet and Monarchy) consider taking them (Mathematics and Iron Working would be good too). We need to back-fill; Animal Husbandry, Fishing, and Sailing at some point, but I would self-research these rather than trade these cheap technologies in light of 'We fear that you are becoming too advanced' issues. Once we have our Monarchy/Theology issue under control, and spend a few turns back-filling, then try to trade as effectively as possible to get Mathematics and Construction. We may need to research Machinery and Engineering ourselves, and this is where growing Istanbul's cottages where possible can help.
Workers: Build that road to connect Karakorum/Beshbalik with the rest of the empire. Help with chopping out planned Buddhist Temple in Edirne, and farm its riverside Grassland. The riverside Grassland tile immediately above Istanbul can be farmed at some point, with the intent of running irrigation to the Corn on the acquisition of Civil Service. If we do acquire Iron Working, then clearing away riverside jungle for farms in Edirne's BFC would be a priority to help feed the Priests.
