Cthulhu Gloom takes the game play of Atlas' Gloom and puts a Lovecraftian spin on it. Each player controls a group of protagonists, and your goal is to make them as miserable and insane as possible – preferably with them dying quickly while your opponents' heroes remain sane and (at a minimum) alive. In the publisher's description: "While your characters Gibber With Ghouls and Learn Loathsome Lore to earn negative points, you'll encourage your opponents to be Analyzed by Alienists and to Just Forget About the Fungus to pile on positive points. When one group finally falls prey to the interdimensional doom that awaits us all, the player whose characters have suffered the most wins."
