Development of Doom
The development of "Doom", a first-person shooter video game by id Software, began in November 1992 and continued until the game was released in December 1993. Seven people worked on "Doom", which is considered one of the most significant and influential titles in video game history. The initial development team was programmers John Carmack and John Romero, artists Adrian Carmack and Kevin Cloud, and designer Tom Hall; late in development Hall was replaced by Sandy Petersen and programmer Dave Taylor was added to the team. The music and sound effects were created by Bobby Prince.
Chex Quest
The development of "Chex Quest" differed from traditional video game development in that the basic game engine had already been created and the bulk of the creation process consisted of aesthetic changes made to the music and artwork from "The Ultimate Doom". For budgetary reasons, Id Software was contacted and an inexpensive license was obtained for the "Doom" engine which was considered obsolete in light of Id's recently released "Quake". "Chex Quest" was the first foray into professional game development for lead artist Charles Jacobi and programmer Scott Holman, though both had previously modded "Doom" levels in the past. In an interview with PC Gamer magazine in 2009, Jacobi stated that the biggest reason for the lasting success of "Chex Quest" has been that it is still essentially a disguised version of "Doom" with basically unaltered game dynamics. Indeed, the game has been recognized for having a sense of humor about its identity and origins.
