So do individuals learn?  I had been thinking about knowledge
graphs, where what every NPC knew was represented by (probably)
trees of concepts.  Then when NPCs talked, subtrees could be
transferred between them, depending on the topic and length of
conversation, with more details transferred as the conversation
progressed.  Kind of like social genetic programs.

If you integrated a basic ecology model.  MOBs could be forced to
move on as population density increased beyond the means of the
local environment to sustain it.
