Everything I Learned About GMing Was With Call Of Cthulhu: Automatic Clues

I got into TTRPGs around the turn of the 1990s and, after my first few games, fell into a long tunnel of Call of Cthulhu gaming. I pretty much exclusively GM’ed Call of Cthulhu from the mid-90s to the late 2000s, including a lot of Delta Green, which back then was a Call of Cthulhu sourcebook.
I wasn’t online much at the time, so all the GMing techniques I picked up during that time were through adventure books, friends, or by myself. I suspect that investigative horror games like Call of Cthulhu are uniquely positioned to force the GM to develop good technique, and that’s sort of what I want to explore here through the lens of my own formative GMing years… and let’s start with “automatic clues!”
