Here's the turn log.
4000BC: Move 1 NW to get more hills, work Camel in starting nine. Very shield heavy spot with two food bonuses. Now this is a start! Already 4spt. Building Ranger in 3. Researching Masonry in 16.
3850BC: Ranger->Ranger First ranger finds double cereal site in near north.
3800BC: Hut=maps.
3750BC: Inca to SE, trade our two techs +1gpt and 10 gold for Masonry and Warfare. Change production to TG in 3.Now researching Pottery in 11.
3700BC: Meet American scout in north - he has no tech to trade.
3650BC: Meet Sioux to NE. He has Cultivation, but won't trade for both our techs.
3600BC: Hun tribe teaches us Boat Building. Trade it to Crazy Horse for Cultivation +14 gold. Trade that and Boat to Abe for Scrape and 35 gold. Sell it to Inca for all his gold (after gifting 25 to improve relations). Same with Crazy Horse. We have two sources of iron and an elephant near Moscow, but not in city limits (if I'd stayed at the starting location, would have had iron!
3550BC: Meet Iroquios to far east. He lacks Masonry, up nothing. Also find horse well to east. Borders expand, now working Pigs.
3450BC: Americans have horses, fairly close by to the north.
3300BC: Meet Aztecs to far west. Trade Cultivation and Alpha for Rit and all his gold.
Trade Abe Potery for Sailing and 60 gold. Writing in 16. Worker Housing->Ranger in 2.
3250BC: Meet England. They are down many techs. Sell them cultivation after gifting gold. Buy two Iroquois workers. We have incense in our borders.
3200BC: Ranger->Archer.
3100BC: Buy Aztec worker. Horses about six tiles south of capital. Archer->Granary in 6 (will need to slow growth one turn to keep granary full)
3050BC: Alemenni tribe teaches us weaving, and we have silks! Silk road, here we come! We trade it to Abe for the wheel, and coffee shows up on nearby mountains - this is very valuable, as it let's mountains give food.
3000BC: Caste System shows up - we can get it in 7 with writing.
Setting up another city for 25K will be tight. Without working the Camel, Moscow can only hold three pop. We may already be too late for this strategy. The overall strategy is to try to time an Oracle build to get Dyna and Philosophy. It may already be too late for that (to get Dyna, not the Oracle.) Doc, some advice there?
If you choose the second city route, here is a plan.
Adjust Moscow to finish granary one turn before growth. Skim a worker off to keep granary full at 3 pop, growing in 5. Build clan timed to growth to 4.
Found city and immediately join our two native workers. Get max shields with those three pop. Shrine is required for Oracle, Forge (and Worker Housing?) should be built before starting it.
The other question, research Myst or let the AI go down that tree?
I believe Oracle and MoM will trigger our GA. Hopefully after we are a Monarchy.
It's a plan, not sure if it's the best one.
