Call of Cthulhu, 3rd Edition [Box Set] - Sandy Petersen, Yurek Chodak, Tadashi Ehara, Harry Henderson I remember playing this a few times during my UCLA days with a group of fellow RPG enthusiasts (this was the era of 2nd Edition AD&D). The one thing I remember about the game was that the longer one's character dealt with the Elder Gods et al. the greater the chances that one would go insane.
