There are only 10 different Space Traits, therefore that means that only the Tribal and Civilization stages affect which one you get. (The 10th one is Wanderer which is the one you get if you start later than Tribal). However all 4 stages give you additional Consequence abilities, which should you have 5 different abilities when you get to the Space Stage.
I've tried to compile a table of how to get certain Space Traits. Ive come up with the following:
(I've only actually tested four, the rest I've made an educated guess)
Tribal + Civilization = Space Trait
Friendly + Religious = Shaman Friendly + Economic = (Guess) Bard Friendly + Military = (Guess) Knight
Industrious + Religious = Diplomatic Industrious + Economic = Trader Industrious + Military = Scientist
Aggressive + Religious = (Guess) Zealot Aggressive + Economic = (Guess) Ecologist Aggressive + Military = (Guess) Warrior
btw I'm quite confident about the Knight Guess, as well as the others
This isn't really true. I've got twice to space stage and twice I got Diplomat but none of the times have I followed the industrious + religious path. 1st one was: herbivore, social, industrious and economic 2 one was: Omnivore, Flexible*, friendly, religious
so it appears that you get Diplomat if you get 2 blue and 2 green ones. I'll do some searching on some other forums, someone has to have the entire list.
