I'm at work currently, so I can't look it up, but if I remember correctly, there are no real rules for PTSD in the game, right?
I'm wondering because I might play this soon with some teenagers, and they tend to be murderhobos, and I would like to have some sort of PTSD function to stress them out about if they start shooting innocent people and the like.
Especially since the world is pretty lawless already, and there's not much in the way of law and order that can come after them.
Sure, I could send "good guys" after them and so on, but I really want to have them suffer some psychological ill effects from being wanton murderers.
