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.
Doom 3
id Software eventually went on to do another remake, this time following the series' original roots in minimal storytelling and fast-paced action. Titled "Doom" and powered by the id Tech 6, the game was released on May 13, 2016 by Bethesda Softworks for Microsoft Windows, Xbox One, and PlayStation 4 with cross-platform support in its "Snapmap" multiplayer mode. A Nintendo Switch version was released in November 2017. Development was announced in May 2008, then slated to run on the id Tech 5 engine and initially titled as "Doom 4".
