Cthonics and Creepers

A GenGame expansion, now off the market. Included sanity mechanics which were also removed from the game, which means that certain current game options have no downsides due to incomplete overhaul of sanity-related elements. Included the Intrepid Investigator and Insipid Investigator spy genres, which still pop up from time to time. Included the Occultist class. The circumstances surrounding the expansion were mysterious and spooky, and elements of it still pop up.
