Dooms first networking implementation was very inconsiderate and had a habit of killing whole networks. https://doom.fandom.com/wiki/Doom_in_workplaces https://doom.fandom.com/wiki/Doom_in_workplaces >The first version of the Doom IPX network code transmitted its data as broadcast data. As a result of this, all machines on a network where a game of Doom was being played would receive the data, even if the machine was not involved in the game. The degrading effect on network performance forced the system administrators for many office networks to ban Doom.
