I think that’s just an extension of the inner ‘min-max’ a lot of players have unconsciously. You play with what the default is but take the “free points” to get the things you want. Sometimes its about a challenge and balancing the challenge. For me, I have a vague character concept and I try to play with that in mind.
For the record, the reason I created this thread is I caught myself making a new toon and taking pyromaniac again. I really enjoy the ‘flavor’ it adds to my “current” character who also has the psychopath trait. I find myself writing little notes about a story on the character. (Maybe I’ll write it out one day if there is a forum for that.) I find myself trying to look at the world from the survivors perspective. “Why can’t I just light this house on fire? Who’s going to catch me? There’s no cops anymore! I can just do whatever I want, social norms are dead and I don’t need to live by their stupid rules anymore! Yet…, what if there is something I need in there? Maybe this time I won’t burn it down… maybe. But next time…, next time I light it up!”
Anyway, I figured if I have a penchant for selecting a specific set of bad traits, perhaps others did too. Sometimes people have really nifty reasons for taking the traits they do. For example, I haven’t tried any of the ‘bad healing’ traits, but now I just might based on the reasons above.
There are also a few bad traits I’ve come to avoid. I had a character with chemical imbalance and Schizophrenic and I had to debug them off because they got to be super annoying.
