How many of you remember Patricia Pulling? She was an anti-occult campaigner from Richmond, Virginia and the founder of Bothered About Dungeons & Dragons (BADD), which was a one-person advocacy group dedicated to the elimination of Dungeons & Dragons and other such games.
How about William Schnoebelen? His essays portrayed Dungeons & Dragons as a tool for New Age Satanic groups to introduce immoral concepts and behaviors.
How about James Dallas Egbert III? After an unsuccessful suicide attempt, he hid at a friend's house for approximately a month. His parents hired private investigator William Dear to find him. Since this detective knew nothing about D&D at that time, he speculated to the press that Egbert had gotten lost in the steam tunnels during a session of a live action RPG. The press largely reported the story as fact. Steve was later found working in Texas.
My point is this: AD&D, rightly or not, acquired a reputation as something dangerous to the minds and morals of young people, thus enhancing its cachet as a 'forbidden' game (much like the game of pool in "The Music Man"). Traveller has no such reputation. Thus, people (especially rebellious teens) looking for the thrill of doing something that their peers and parents would not approve of, will gravitate toward something 'naughty' like AD&D - and not 'thoughty' like Traveller.
Is any of this germane today? Besides old school folks like us that lived through the 80's, does anyone even recall this stuff any more?
