So, what traits have people managed to unlock, and how do you think you got them?
So far, I have:
Ground stone tools (bonus to crafting) - 500 knapped tools
Ritual Necrophagy (unburied corpses turn into edible meat. O.O ) - don't know, enough people died?
Fear of death (unburied corpses cause double unhappiness) - don't know, enough people died?
Joy of eating (eat more food but gain more happiness) - Plentiful food rations for enough years
Artistic thinking (culture gain bonus) - don't know
Insect eating (eating bugs no longer causes unhappiness) - Insects as food policy for enough years
Scavenging (idle workers gather some resources) - don't know, enough time with idle workers?
Rules of food (unlocks food policies) - enough time passed in game
Edit: just got "belief in the afterlife" (half unhappiness from corpses) I think from having 75 soothsayers. Still have "fear of death" so... not sure what net result is. Default unhappiness from corpses?
Edit edit: and now "belief in revenants" (double unhappiness from corpses) so really confused about net fear from corpses.
