Nathaniel L’s Reviews > Stealing Cthulhu > Status Update

Contains interesting advice for making Cthulhu stories more genuinely Lovecraftian: bleak, horrific, and dreamlike. Covers many topics: patterns like increasing harm, Mythos creatures like shoggoths, and locations such as catacombs.
Better than "Play Safe." Worth reading though I found the marginalia -- by Gareth Hanrahan, Ken Hite, and Jason Morningstar -- often better than the core text.
