What generates gems?

[JimMorrison]

I started all nations with even scales other than luck, putting all remaining points into Dominion with an awake pretender, most were 9-10 Dom. I did not look at them until the end, didn't make PD or build anything, and didn't recover lost provinces.

After 20 turns running, starting with 9 provinces -

Arcoscephale - 3 Luck

Totals -

Luck Group:
Provinces - 50
Gold - 116519
Gems - 1054 (Net 334 after 720 base income at capital)
Heroes - 4

Control Group:
Provinces - 16 (x3 = 48)
Gold - 34486 (x3 = 103458)
Gems - 315 (x3 = 945) (Net 75 after 240 base income)
Heroes - 1 (3)

Misfortune Group:
Provinces - 44
Gold - 102371
Gems - 927 (Net 207 after base income)
Heroes - 1

Disparity between Luck/Misf over 20 turns (per nation)=
Provinces Lost = 1 (5% greater chance)
Gold Income = 14148 (2358/nation, ~120/turn including territorial losses)
Gem Income = 127 (21/nation, ~1/turn including random lvl 0 sites in starting provinces)
Heroes = 3 (.5/nation, not statistically relevant to known formula due to small sample size)


I really think I might run more tests later, using all EA nations at each level of Luck/Misf, 1 at a time. I'll have to be bored to do it, but that happens plenty often enough.
