The game is afoot! I am going into detail a bit... if you feel that is not necessary, just let me know
Early moves
I sent the settler NW to get a mountain view, but this did not give sufficient reason to not move N next turn and found Entremont on the regular grass tile. Meanwhile the worker moved to the BG and started mining + roading it, then moved to the wheat to improve it.
The settler factory
On size 5:
Center: 1 shield
Wheat irr: 0
BG mined: 2
Pl irr: 1
Pl irr: 1
BG: 1
Total: 2x6 + 2 (forest on growth) = 14 shields
On size 6 we work another irrigated plains, giving 2x7+2 = 16 shields. Total 30 shields per 4 turns.
This setup requires careful MM. Note that the second BG does not need to be mined. Make sure 'emphasize production' is on.
Research
F10 Space race view reveals our adversaries: Japan, Babylon, French, Mongols, Carthage, China, English, Iroqois, Indians, Vikings and the Americans. Between them, all starting techs are covered, so I start Mysticism with the slider as high as possible.
Production
Two warriors, both sent out to explore. When my 20 turns are up, the first spots some borders, the Chinese I would guess from the color. Also noteworthy is the other wheat in the northeast of Entremont and the silks nearby.
Since the wheat makes us grow like crazy and the start is so rich in food, I decide to get out an early settler, which is sent to the northeast for another settler factory. Next up is a granary... we should carefully time it's completion so the next settler will be finished without having grown beyond size 6.
