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 (2016 video game)
Initial reception of the QuakeCon 2014 trailer accumulated considerable acclaim among fans, and initial reception of the E3 2015 trailer was also positive, despite receiving criticisms by some critics, who considered the game to be too violent. Pete Hines from Bethesda Softworks responded by saying that the game is designed to allow players to apply violence on demons instead of humans. Hines added that, "if you're not into violent, bloody games... "Doom" probably not a game for you."
