Stealing Cthulhu (PDF)
Many Cthulhu games feel the same. You shoot cultists. You do rituals. You unearth a buried god that's like every other god you've dug up. This book shows you how to make your games new and horrifying: by stealing from H. P. Lovecraft.
Stealing Cthulhu is my guide to Lovecraftian storytelling for roleplaying games. Its central idea is: by stealing, adapting and combining Lovecraft’s ideas, you can create scenarios that seem new and horrific. It includes Cthulhu Dark, my rules-light system for Cthulhu gaming.
