The means to make it is there! If you disagree with me go ahead and say why, but we have Agoraphobia and Claustrophobia, so why not a couple of Disorders? it could be a fun game to have a character have his mood randomly fluctuate from the tiniest things, and you may say you can just take Short Tempered, but I don't really agree because that only makes it easier to become angry and unhappy, and if you would take this trait, it should cancel out the ability to take Short-Tempered or Patient. This game has alot of psychological-stuff planned so a couple of things like this would probably fit right in, imagine the difficulties one could have joining a survivor group with this, would make for a very interesting game! And if anyone finds this post offensive, i'm uhh...sorry, I didn't mean to offend and don't see how I did. And for you old-timers, i'm sorry if this was suggested before, really I am. Thanks for reading!
