Doom (1993 video game)
The ability for others to create custom levels and otherwise modify the game using WAD files turned out to be a popular aspect of "Doom". Gaining the first large mod-making community, "Doom" affected the culture surrounding first-person shooters, and also the industry. Several future professional game designers started their careers making "Doom" WADs as a hobby, among them Tim Willits, who later became the lead designer at id Software.
1990s in video gaming
In 1992 "Wolfenstein 3d" is released, creating interest in what fps games could become. "Doom" (1993) bursts onto the world scene and instantly popularizes the FPS genre, and even how games are played, as Doom is among the first games to feature multiplayer capabilities. It was "Goldeneye 007" (1997), that introduced an engine that made development of first-person shooters for home consoles a practical idea. It is not until "Quake" (1996), however, that game developers begin to take multiplayer features into serious consideration when making games. "Quake II" (1997), "Unreal" (1998) and "Half-Life" (1998) feature the next evolutionary step in the genre with continual progression of the game (no levels in the traditional sense) and an entirely in-person view, and become one of the most popular video games in history.
