(1) This FAQ is awesome - I'd love to see Firaxis put a lot of it in their manuals
(2) In the Culture Flip Formula :
the full formula (this is from Sorenson, who is responsible for this programming):
P=[(F+T)*Cc*H*(Cte/Cty) - G]/D
where:
P = probability that it will flip this turn
F = # foreigners, with resistors counting double
T = # working tiles under foreign control
I recall the folks at Firaxis stating that the #foreigners, and the tiles under foreign control, refer SPECIFICALLY to the civ where the flip would be to, not just any civ. For example, if Japan has 6 of my 21 tiles in their control, or if I have 4 Japanese citizens in my city, these won't help the odds of a flip to Rome.
Does anyone know this for certain? If this is true, maybe we can adjust the formula in the FAQ to be more specific.
