The legendary first-person shooter DOOM was born from a Dungeons & Dragons game gone wrong.

In short: DOOM is more than a game; it is a cultural phenomenon that defined the first-person shooter genre. While its technical innovations changed PC gaming forever, its creators claim the project might never have existed if not for a disastrous session of Dungeons & Dragons that set the team on a new path.

Released on December 10, 1993, DOOM transformed the landscape of computer gaming. Developed by id Software—a company founded in 1991 by John Carmack, John Romero, Tom Hall, and Adrian Carmack—the game built upon the success of their earlier hit, Wolfenstein 3-D. While Wolfenstein popularized the first-person perspective, DOOM introduced realistic floor and ceiling textures that significantly enhanced the sense of embodied movement. Though the narrative was sparse, focusing on a lone player blasting aliens on a military base, its impact was immediate and immense.

The game’s success was driven by revolutionary distribution and technical openness. id Software utilized a shareware model, releasing the first episode for free to generate word-of-mouth buzz. This strategy was so effective that the initial release on University of Wisconsin servers crashed the entire system. Furthermore, John Carmack made portions of the source code public, empowering a dedicated fan base to modify the game’s graphics and levels. This culture of accessibility, combined with the game's frenetic gameplay, made it a ubiquitous presence on PCs worldwide.

However, the game’s legacy is complex. Following school shootings in the late 1990s, including the tragedies at Columbine and Heath High School, DOOM and its successor, Quake, faced intense scrutiny. Critics and families of victims argued the games functioned as training simulations for violence. A $130 million lawsuit was filed against id Software and other companies, alleging the games influenced shooters like Michael Carneal. While the case was eventually dismissed in U.S. District Court, the controversy highlighted the profound, and sometimes contentious, influence that digital environments began to exert on public discourse and real-world behavior at the turn of the millennium.
