"Doom" became a problem at workplaces, both occupying the time of employees and clogging computer networks. Intel, Lotus Development, and Carnegie Mellon University were among many organizations reported to form policies specifically disallowing "Doom"-playing during work hours. At the Microsoft campus, "Doom" was by one account equal to a "religious phenomenon". Doom was #1 on "Computer Gaming World"s "Playing Lately?" survey for February 1994. One reader said that "No other game even compares to the addictiveness of NetDoom with four devious players! ... The only game I've stayed up 72+ straight hours to play", and another reported that "Linking four people together for a game of Doom is the quickest way to destroy a productive, boring evening of work".
