In Cthulhu Gloom, you control a group of Lovecraftian protagonists and guide them down a path of horror and madness to an untimely death, while keeping your opponents annoyingly alive. While your characters Gibber With Ghouls and Learn Loathsome Lore to earn negative points, you'll encourage your opponents to be Analysed 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.
