A REALLY BIG ROLE PLAYING GAME [] In 1981 two role playing game designers, John Diaper and Larry Flournoy of Theatre Of The Mind Enterprises, Inc. (TOME, producers of adventures for Call of Cthulhu, Stormbringer and Tekumel games) decided to create a full scale, real time role playing game based upon a murder mystery. They thought that they would attract "gamers" to their new venture, but, to their amazement found that it had much greater appeal to the general public. They soon realized that they had created a new entertainment genre which they coined "Living Theatre".
