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).
Castle Falkenstein (role-playing game)
"Castle Falkenstein" was ranked 45th in the 1996 reader poll of "Arcane" magazine to determine the 50 most popular roleplaying games of all time. The UK magazine's editor Paul Pettengale commented: ""Castle Falkenstein" is one of those games that people tend to either love or hate. It has a unique atmosphere, combining alternate history, celtic mythology, steampunk and a somewhat whimsical, fairy-tale feel. Likewise, the rulebook itself is quite different from many, being laid out as a novel, with important information pulled out in sidebars, and the rules coming later. This reflects the main thrust of the system, which is heavily geared towards roleplaying and storytelling over game mechanics and numbers, and drops dice in favour of a couple of packs of playing cards."
