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.
Tim Willits
Willits has stated in numerous interviews that he was inspired to make video games when he downloaded a shareware version of "Doom". He played the first room of Level 1, thinking that was the entire demo, then, discovering a door that led the player to the other rooms. It was that moment when the door opened, Willits was transported into making video games. Willits required assistance with developing doors in future levels and games. He joined id Software in 1995 after impressing the owners and development team with Doom levels he forged in his spare time and distributed free over the Internet. Willits has worked on "Strife", "The Ultimate Doom", "Quake", "Quake II", "Quake III Arena", "" and "Doom 3".
