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.
List of Doom source ports
The "Doom" engine's source code was released to the public on December 23, 1997. Although "Doom" was originally created for MS-DOS, the original source release was for the subsequent Linux version, due to the use of a proprietary sound library in the DOS version. The original purpose of source ports was cross-platform compatibility, but shortly after the release of the "Doom" source code, programmers were correcting old, unaddressed "Doom" bugs and deficiencies in their own source ports, and later on introducing their own modifications to enhance game features and alter gameplay.
