Just some thoughts that I'd like to hear opinions on from those with some experience with the game. Let's talk about stress and insanity.
From just a reading of the rules it seems to me that mostly spell casters really have to deal with stress. Unless you're running a lot of extended social encounters (I plan to feature this as much as possible) I don't see many characters having to draw upon mental skills in a way that would accumulate stress in a significant manner.
Even if you do use a lot of extended social encounters and stress accumulates, most of those situations aren't really going to be Insanity worthy. Right? So is insanity something that you mostly see spell casters having to deal with?
Or, do fear and terror play large roles in your games, making stress and Insanity a concern for everyone?
