I not sure which subcategory this should go under, but how will the game handle the Psychology of organisms and their feelings, assuming this something that is added later on?
For instance, loss of a tribal member in Tribal Stage. Or an organism has to runaway from forest fires in Sentient Stage. These traumatic events can negatively affect the mental health of an organism, and continue to affect the organism long after the event has passed.
And this is just examples of negative Psychological events. What about positive Psychological events?
