Wolfenstein
The "Wolfenstein" series of video games started with the 1981 stealth-adventure video game "Castle Wolfenstein". It was developed by American programmer Silas Warner, a pioneer in the early eras of video gaming, especially the stealth genre. It was published by his (then) company M.U.S.E. Inc. (Muse Software). The player controls an unnamed American prisoner of war as he steals war files containing information about secret German war plans while avoiding or sometimes killing guards, and tries to escape the fortified Nazi stronghold Castle Wolfenstein, set during World War II. The game is often credited as one of the first video games of the stealth genre, since it focuses more on avoiding or disarming enemies, and killing them is considered a last resort.
Mike Pondsmith
In 1994, R. Talsorian Games released Pondsmith's steampunk-themed fantasy role-playing game titled "Castle Falkenstein". The game's mechanics were based on playing cards, instead of dice, and geared towards live action role-playing. "Castle Falkenstein" remains Pondsmith's most critically acclaimed game to date with the 1994 Origins Award for Best Roleplaying Rules, and the 1995 Nigel D. Findley Memorial Award for Best Role-Playing Product recognitions. In 2000, "Castle Fankenstein" was adapted to the "GURPS" system by James Cambias and Phil Masters, and released by "Steve Jackson Games".
