So, here we are at round 32:
I chose to do, what lymond said.
I settled A1 and let the worker farm the dye. This way the new city can use the floodplain and the old city can use the dye after growing to 2 again. After it has grown to 2, I build worker again, which I plan to whip, not to chop. The free worker will build the Pasture.
I decided for Pottery, for granary and cottages.
What would you do with the floodplains? Cottage 'em or farm 'em?
Thinking "growth is everything" would mean to farm is better, but a cottaged floodplain is very strong longterm and starts here with 3C. My guts are saying: "Cottage it".
What would you say?
Now, we have to answer 3 questions now:
1) When do we want to build the second settler? I would say, directly after the second worker and regrowth to pop2.
2) Where should we place the 3rd city? I would take B1 or 1N of it. In turn 50 this city could use the floodplain west of Djenne
3) What should the workers do in witch sequence? I would build the pasture next and after the next worker has finished, we have to see further.
One warrior is scouting the east now. If there's a better place, maybe with elephants or very food-rich, I would consider to settle there, defending with skirmishers.
Edit: It was eaten by a strong team of an bear and a lion. Rest in peace, my friend.
___________________________
Most of the next turns are straightforward, when we accept building the second worker is the best after regrowth: Now round 39.
We need to decide, what the worker and the worker #2 will do: I would say, cottage the floodplain, but it's possible to mine the gold too or to farm the floodplain. Maybe the worker could chop the forest NW of Djenne to make this process faster.
Additionally we need to decide, what Djenne will build. I would say, an worker. Timbuktu needs regrowing and thenafter should build a settler, right?
I chose Writing as next tech, so it would be possible to build lib too because of the massive commerce of 16 in cap (after regrowing). Only drawback: There's nothing really good to research with these crappy tiles. Best would be maybe hunting/archery and thenafter ironworking to get known more about the map. When I plan to take copper or to expand Djenne to the oasis, Mysticism can be a thought worth.
Cap will expand in 11 turns.
