“One of the most difficult tasks men can perform, however much others may despise it, is the invention of good games and it cannot be done by men out of touch with their instinctive selves.”
– Carl Jung
Original, 0e, “White Box” D&D was impossible to learn to play by just reading the rules. You had to have someone else, who had been taught by someone else, teach you how to play. D&D was, at that sweet, sweet point in the ’70s, an initiatory system. Someone taught you and, if you were like me and the game “possessed” you, you went on to teach others.
So it went.
