Call of Cthulhu, and The Rules Of The Story
You’ve probably heard of Call of Cthulhu if you’re involved in RPGs at all. Released in 1981 by Chaosium, the system is based on the works of H.P. Lovecraft. Usually set in the early 1900s, the game centers around investigators, artists, professors, and other similar protagonists of H.P.’s stories, discovering and hopefully thwarting the machinations of cultists, Old Ones, and horrors from beyond. It’s famous for having a high body count; do not fall in love with your characters, they will die or go mad with remarkable speed.
