Too late post, Obormot - I already played. Just 10 turns, so we can make main descision later.
First 10 turns we must not meet barbs, so I try to scout in 2 directions. I think we can walk around 10 turns ang research Misticism fast. Interesting thing: Tokyo already has 1 culture point...
4000BC Warrior go East on the Hill. See Sheeps and Gems. Settler go SW-NW on the coasrline. Capital build Work Boat.Research Mysticism.
3970BC Warrior go SE on Plain Hill. See more Gems and Oasis. It looks like very good place. Settler go SW-S along coast.
3940BC Warrior met Isabella's Scout. Warrior go SE. Settler go SW-SE.
3910BC Warrior go SE, see the Hut. Settler go SE on the Hill, met second Isabella's Scout, very interesting. Now it looks like we have no vay to West and Tundra on South.
3880BC Warrior go SW on the Hut and got Mining! Settler go SE-SE.
3850BC Warrior go SE. Settler go SE-NE. I think the best place near the Gems, so go North.
3820BC Warrior go SE. Settler go NE-NW.
3790BC Warrior go SE. Settler go N-N. Tokyo borders expand, see 2 islands on north with Stone and Cow.
3760BC Warrior go NE. Settler go NW-NE.
3730BC Warrior go N. Settler go N on the spot for future city.
3700BC Mysticism discovered, decision point.
If we settle here we will get corruption around 8 but we have Oasis in radius 1 and 2 Gems in the future. Also it's Plain Hill - 2 Hummers in the centre. About next tech - I selected Poly, but it will be too long to discover... may be we need other way - let's discuss.
