If you want to explore the potential strangeness of the world around you, influenced by the weird fiction of H.P. Lovecraft and similar writers but unconstrained by rules, campaign settings, dice, or character sheets, you might enjoy giving De Profundis a try. Role-playing games are sometimes described as "let's pretend with rules." It's probably better to think of De Profundis as offering a "social contract for shared storytelling." I have to admit that the experience doesn't really appeal to me very strongly; I'm too much of a mechanics wonk. However, I enjoyed reading the book. It's written in a very engaging style that actually mimics the experience of playing De Profundis, and it successfully draws the reader into a fictional world where the game itself is a character. If you find traditional role-playing games too "dicey" but you're not really interested in the costumes, props, and constraints of a LARP—and you sense that the weird hides just behind the veil of the normal—take a look at De Profundis. Maybe psychodrama is for you.
