Dangerous Journeys

Dangerous Journeys was a roleplaying game created by Gary Gygax, the co-creator 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 co-founded, over objections that the DD abbreviation would be too similar to "D&D."
Created after his departure from TSR, the publication of this series of books by Game Designers' Workshop (GDW) was met with lawsuits by TSR, which ultimately saw the production of the game system cease.
The design of the game system addressed many of the perceived flaws and limitations of the older AD&D game system, such as a lack of a skill system and rigid, class-based restrictions on weapons. According to a FAQ on the official Gary Gygax website, the "Mythus Fantasy" setting for "Dangerous Journeys" was one of several settings planned for the system.
Several books were produced for the line:
At least one additional game in the "Dangerous Journeys" series was planned but never published:
Electronic Arts began to develop a video game version, but it was never completed.
