Ok, so I would propose:
I would play another 8-ish turns, I think, which should be marble city founded, chariots past DG borders, and hopefully western explorers revealing something interesting.
- Moscow builds cha-cha-str(marble)-str(pigs). After that, we could build a granary and grow, I think, but it's well beyond the scope and open to discussion.
- Finish Currency and start on Calendar @ 0% slider. Keep 0% until academy.
- Trade Currency to Gandhi a.s.a. he has reasonable trade bait (something like IW to go with Poly & Masonry would be nice).
- Hold Currency back from Roos.
- North workers: fairly straightforward - get food tiles going asap.
- South workers: ensure that the city site is ready and pig ready to pasture in time for settling. Otherwise, road further west with spare turns.
- Moscow workers: irrigate rice.
