Wolfenstein
Silas Warner, an American programmer and an employee of software company Muse Software, was a pioneer of early video game development, especially the stealth genre. He had access to computers in college, and when he worked for the IBM Mainframe architectures before joining Muse Software. The computer he used for game-development, P.L.A.T.O., was one of the firsts with multiple functioning terminals and an example of early computer networks. Warner developed, with P.L.A.T.O., a series of classic video games like his flight simulator and arcade shooter. Inspired by the arcade shooter video game "Berzerk" and the 1961 war film "Guns of Navarone", he developed "Castle Wolfenstein", a stealth-adventure video game in which the player controls an unnamed American prisoner of war as he steals German files containing secret war plans, while avoiding, disarming or at times killing hostile guards and trying to escape the fortified Nazi stronghold 'Castle Wolfenstein', set in World War II. The game was published in 1981 by Warner's company M.U.S.E. Inc. (Muse Software).

Ron Gilbert has been working with adventure games since his days at LucasArts, including several collaborations with Tim Schafer and Dave Grossman; together, they developed games like "Maniac Mansion", its sequel "Day of the Tentacle", and the first games in the "Monkey Island" series. Gilbert left LucasArts in 1992, initially creating his own development studio but then moving on to other games, including contributing to Telltale Games' episodic series, "Tales of Monkey Island" based on the LucasArts series. Meanwhile, Schafer would stay with LucasArts until the adventure game market fell in the late 1990s, and created his own studio, Double Fine Productions, with several of the former LucasArts developers. Though Double Fine struggled with well-received but financially unsuccessful titles "Psychonauts" and "Brütal Legend", it became successful in marketing four smaller games developed during an "Amnesia Fortnight" period in "Brütal Legend"s development between 2010 and 2011.
