Mysterium
Are the suspect, location and object cards assigned to psychics at random?
Several posters quote the original setup text and agree the assignment is meant to be random; the current rulebook wording is less explicit.
That is the intent. The psychic cards are shuffled and drawn, and the ghost should not pick who gets which. The rulebook only says the ghost assigns one card to each Psychic, so letting the ghost choose is a house rule.
