I wonder if it makes sense to add another quirk to a future game. The role of the psychic has been pretty standard. What if the psychic leaves a mystical icon emblazoned on the door of the person that he inquires about? It won't indicate whether that person was an innocent or a werepenguin, it would just indicate that the psychic had inquired about them.
I think that would be a neat twist. I won't be doing it in this game, because it's underway. But maybe next game it would be fun to add.
I like the exorcist role, too, based on the traditional Faith Healer from the Mafia game, but Shifter really ate a big dong on that one...
