Dangerous Journeys

Dangerous Journeys was a roleplaying game created by Gary Gygax, the cocreator of the original Dungeons & Dragons system. The game was originally announced as Dangerous Dimensions but was changed to Dangerous Journeys in response to a threat of a lawsuit from TSR, Inc., the publishers of Dungeons and Dragons, and the company Gygax had cofounded, over objections that the "DD" abbreviation would be too similar to "D&D."
