From the Introduction:
You sense things no one else can. And you use your gift to help the authorities catch dangerous criminals. Today you’re teaming up with other consultants with mysterious talents, despite your many differences. What twisted plot demands the collaboration of such odd detectives?
Psychic Detective Agency is an American Freeform game for 2 or more players, based on improv fundamentals. Take on the role of psychic detectives, and shape the story together. Your characters might see the end coming, but you never will.
What is American Freeform? It's sort of like Live Action Roleplay (Larp), crossed with improv, and generally focused on intense, single session games. You'll know it when you see it.
Gameplay: As a group, you create the story together by answering Questions and then playing out scenes. Anyone may prompt a Question at any time. Players are not restricted to narrating or roleplaying only when prompted, but have greater narrative authority when answering a Question.
