Role Aids is a line of role-playing game supplements published by Mayfair Games starting in 1982 .
Role Aids products were intended for use with Advanced Dungeons & Dragons.
As a veteran role-playing gamer, Bill Fawcett decided to get Mayfair Games into the RPG field, and the company kicked off its Role Aids game line with Beastmaker Mountain (1982).Darwin Bromley was involved with the Chicago Wargaming Association's convention, CWAcon, where Mayfair's first fantasy adventures in their new Role Aids game line were run: Beastmaker Mountain, Nanorien Stones (1982) and Fez I (1982). With Bromley's legal expertise, he felt that Mayfair could legally use TSR's trademarks as long as they were careful, so beginning with their Dwarves (1982) supplement Mayfair made it clear that they were not the trademark holders by printing on the cover: "Advanced Dungeons & Dragons is a trademark of TSR Hobbies, Inc. Use of the trademark NOT sanctioned by the holder."
Gary Gygax had advocated arranging a licensing agreement between TSR, Inc. and Mayfair Games for their Role Aids line of game supplements, but was outvoted in the board meeting considering the question.
In the early 1990s, Ray Winninger resurrected the Role Aids line, determined to recreate it with AD&D material that was more sophisticated than what TSR was offering at the time.
In 1993, Mayfair was sued by TSR, who argued that Role Aids—advertised as compatible with Advanced Dungeons & Dragons—violated their 1984 trademark agreement. While the court found that some of the line violated their trademark, the line as a whole did not violate the agreement, and Mayfair continued publishing the line until the rights were bought by TSR.
