First, the dotmap I made before playing, some spot are obsolete now.
PreTurn: nothing
IBT: Gilgamesh friendly asks us to leave; Cuzco settler-barracks
1725BC: exploring, lux to 10, research to 90
IBT: Sumeria learns polytheism, but we have nothing to offer
1700BC: we spot another goody hut; I move the warrior out of Machu Picchu - that will stop it growing, but we need to look for iron there and our scouts did miss scouting our lands before veturing to foreign lands
IBT: Xerxes kindly asks us to leave
1675BC: get a warrior from the hut
IBT: Persia starts The Oracle
1650BC: movement
IBT: Xerxes speeds us through his territory; our conscript defeats two barbs and is now a veteran
1625BC: we meet the Maya behind Persia - they are down writing; warrior from a hut spots a village; scout spots another one and a source of iron at Sumerias; we find an iron ne of Machu Picchu; Ollantaytambo founded at the elephants; lux to 20, research to 80 - philosophy in 1
IBT: we learn philosophy take code of laws for free and start the republic at 10%; Cuzcu barracks-settler
1600BC: we meet Isabella - she misses writing and Wang Kon - he is up maths and misses philosophy and code of laws; temporarily switch settler build and research, but huts only give us a map and 50 gold nonetheless

We trade: philosophy + 1gold to Persia for horseback riding; philosophy + 81gold to Korea for mathematics; Sumeria still wants an arm and a leg for polytheism - no trade
IBT: we spot 2 more ivory to the east - we may want to claim them
1575BC: nothing
IBT: Machu Picchu worker-worker
1550BC: nothing
IBT: Cuzco settler-archer; Korea starts The Colossus; Spain the Oracle
1525BC: lux to 10%; reseach to 40%
IBT: Ollantaytambo warrior-worker; polytheism was passed around
1500BC: settler moved in position to claim the horses for us, we could start some horsemen (change archer in Cuzco to horse (!?) - seems a good choice on this map. Continue settling, we are losing land to the AI. Have a look at buying poly - the trade should get us some more gold than the 99 in our treasury. You may want to adjust research too.
Good luck!
