Dirk Gently's Holistic Detective Agency: Everything is Connected is the first in a series of "Everything is Connected" storytelling games in which the mysteries are only as looney as the players.
In this game, a detective and a holistic detective put together the clues, accuse a person of interest, and tell their assistants the story of the crime. The assistants then process the two versions of the case and simultaneously select which version of the truth is more believable. To solve the case, you have to think on your feet and remember that "everything is connected".
