Call of Cthulhu/YMMV


 * Fan Nickname: Gnarly (Nyarlathotep), Buzz (any individual Mi-Go) ETs (Elder Things), etc.
 * Memetic Mutation: SAN check.
 * "Cthulhu eats 1d4 adventurers per round."
 * "You're dead. And crazy."
 * IA IA CTHULHU FHTAGN!!!
 * ARGH, MY EYES
 * MAN THE HARPOONS
 * Old Man Henderson. Just... Old Man Henderson. That's really all there is to say on the matter.
 * High Octane Nightmare Fuel: All the typical Lovecraft stuff; cosmic horror, zombies, unfathomably ancient aliens etc...But then consider all the other mythos writers' creations that show up...And then add in some of the scenario writers' creations.
 * Y'Golonac. Just Y'Golonac. (YOU FOOL! YOU'VE DOOMED US ALL!!)
 * Only if sock puppets are involved.
 * The monster that causes the problems in the scenario . A particularly graphic description plus the investigators realising just how big it is can call for a pretty rapid exit strategy from the characters. And the players.
 * The scenario The Colour of his Eyes from the San Francisco sourcebook. A man has a Colour Out Of Space (basically a form of sentient, malevolent light) trapped in his eyes, and he drains the energy from (and kills) anything he looks at.
