Someone, something, or some goal constantly weighs on the character’s mind. It may be just keeping track of time, doing things in threes, or it could be something as strong as the need for revenge or the love of a special someone. Having the Obsession trait is rarely something helpful, and this Bad Trait is uncommon in player characters. This sort of fanaticism is best suited to people like Missy or the Half-Face Man.

As a Minor Bad Trait, it means the character has a mild obsession, a bit like Clive and his investigation into the Doctor. It doesn’t creep into every part of their lives, but it’s always there, itching at the back of their minds. Their obsession isn’t strong enough to be too troublesome, but there are times when they simply have to do something because of their compulsion. Often, this isn’t anything too drastic, like switching the gas on and off again before leaving a house, checking their emails every hour or needing to wear a certain pair of underwear on Wednesdays. They can try to resist acting upon their obsessive nature with an Ingenuity and Resolve roll, suffering a -2 penalty.

As a Major Bad Trait, the character is crazed with determination to do something. Almost every action or plan is designed to get them closer to achieving their aim, whether this is galactic domination or acquiring vast amounts of wealth. At this level, it is not usually suitable for player characters.
