Question: Cyborg Commando is a science fiction role-playing game (RPG) published by New Infinities Productions, Inc in 1987 and designed by Kim Mohan, and which American fantasy author and game designer best known for his work on early materials for the "Dungeons & Dragons" (D&D) fantasy role-playing game?
Context: Jacob Franklin "Frank" Mentzer III (born in 1950), is an American fantasy author and game designer best known for his work on early materials for the "Dungeons & Dragons" (D&D) fantasy role-playing game.  He was a performing folk musician from 1968 to 1975, and played one concert at the White House during the administration of Richard Nixon.  He was an employee of TSR, Inc. from 1980–1986, spending part of that time as Creative Advisor to the Chairman of the Board, Gary Gygax.  He also founded the Role-Playing Games Association (RPGA) during his time with TSR.  He has been closely involved with the world's largest game auction at the Gen Con game convention since 1983, and is an expert on, and a major collector of, family boardgames and role-playing games.  After Gygax was ousted from TSR at the end of 1985, Mentzer left TSR as well and helped him to start New Infinities Productions Inc. (NIPI).  When this venture failed, Mentzer left the gaming industry, eventually becoming the manager of a bakery.  In 2008, he closed down this business and, two years later, announced he was returning to the gaming industry as a founding partner of a new publishing company, Eldritch Enterprises. David Lance "Dave" Arneson (October 1, 1947 – April 7, 2009) was an American game designer best known for co-developing the first published role-playing game (RPG), "Dungeons & Dragons", with Gary Gygax, in the early 1970s.  Arneson's early work was fundamental to the development of the genre, developing the concept of the RPG using devices now considered to be archetypical, such as adventuring in "dungeons" and using a neutral judge who doubles as the voice and consciousness of all other characters to develop the storyline. Empire of the Petal Throne is a fantasy role-playing game designed by M. A. R. Barker, based on his Tékumel fictional universe, which was self-published in 1974, then published by TSR, Inc. in 1975.  It was one of the first tabletop role-playing games, along with "Dungeons & Dragons".  Over the subsequent thirty years, several new games were published based on the Tékumel setting, but to date none have met with commercial success.  While published as fantasy, the game is sometimes classified as science fantasy or, debatably, as science fiction. Metamorphosis Alpha is a science fiction role-playing game.  It was created by James M. Ward and originally produced by TSR, the publisher of "Dungeons & Dragons".  It was the first science fiction role-playing game, published in July 1976. Forgotten Realms is a campaign setting for the "Dungeons & Dragons" ("D&D") fantasy role-playing game.  Commonly referred to by players and game designers alike as "The Realms", it was created by game designer Ed Greenwood around 1967 as a setting for his childhood stories.  Several years later, Greenwood brought the setting to the "D&D" game as a series of magazine articles, and the first Realms game products were released in 1987.  Role-playing game products have been produced for the setting ever since, as have various licensed products including sword and sorcery novels, role-playing video game adaptations (including the first massively multiplayer online role-playing game to use graphics), and comic books.  The Forgotten Realms is one of the most popular "D&D" settings, largely due to the success of novels by authors such as R. A. Salvatore and numerous role-playing video games, including "Pool of Radiance" (1988), "Eye of the Beholder" (1991), "Baldur's Gate" (1998), "Icewind Dale" (2000) and "Neverwinter Nights" (2002).

Robert N. Charrette (born 1953) is an award-winning graphic artist, game designer, sculptor and author.  Charrette has authored more than a dozen novels.  His gaming materials have received many Origins Awards.  Charrette was inducted in the Origins Hall of Fame in 2003.  His work is known for a clean, realistic style that invokes themes from Feudal Japan and Chanbara films and in particular, historical and fantastic representations of Samurai culture.  His early work in game design and miniature sculpting set the tone for depictions of Japanese mythology in American fantasy and science fiction.  His 1979 role-playing game "Bushido" was one of the first role-playing games with a non-Western theme and remained in print for more than three decades.  Charrette produced gaming products for Fantasy Games Unlimited, Grenadier Models Inc. and Ral Partha Enterprises, FASA and currently operates Parroom Enterprises, LLC, a boutique miniatures game company. Dwellers of the Forbidden City is an adventure module, or pre-packaged adventure booklet, ready for use by Dungeon Masters in the "Dungeons & Dragons" ("D&D") fantasy role-playing game.  The adventure was first used as a module for tournament play at the 1980 Origins Game Fair, and was later published by TSR in 1981 for use with the first edition "Advanced Dungeons & Dragons" rules.  The module was written by game designer David "Zeb" Cook, who partly ascribes his hiring by TSR to his work on this module.  In the adventure, the characters are hired to find an object taken to a lost oriental-style city, which has been taken over by a cult of snake-worshipers, the yuan-ti, and their servants, the mongrelmen and tasloi.  The module was ranked as the 13th greatest "Dungeons & Dragons" adventure of all time by "Dungeon" magazine for the 30th anniversary of the "Dungeons & Dragons" game in 2004.
