Mysterium

As part of a spooky games series in the runup to Halloween, io9 looks at Mysterium, a board game in which most of the players try to help a ghost, and one player plays the ghost... who can’t tell them what it needs, except through cards depicting largely surreal or abstract visions. So it’s kind of like Cluedo as you try to solve a mystery, except one player knows the secret and has to play Pictionary. In a haunted house. That’s a pretty interesting twist on the cooperative board game.
