GMT Games
GMT Games is a California-based wargaming publisher founded in 1990. The current management and creative team includes Tony Curtis, Rodger MacGowan, Mark Simonitch, and Andy Lewis. The company has become well known for graphically attractive games that range from "monster games", of many maps and counters, to quite simple games suitable for introducing new players to wargaming. They also produce card games and family games. "The Washington Post" called GMT "the modern hobby's highest-profile wargame publisher".
RPGA
Frank Mentzer, one of the first full-time employees of TSR, Inc., the original publishers of the Dungeons and Dragons game, conceived of the Role Playing Game Association (RPGA) in order to promote quality roleplaying and to allow fans of roleplaying games to meet and play games with each other. Mentzer founded RPGA in November 1980 primarily to run tournaments at gaming conventions using TSR's top sellers: "AD&D", "Gamma World" and "Top Secret".
