Doom (1993 video game)
Doom (typeset as DOOM in official documents and stylized as DooM in other media) is a 1993 first-person shooter (FPS) video game by id Software. It is considered one of the most significant and influential titles in video game history, for having helped to pioneer the now-ubiquitous first-person shooter. The original game was divided into three nine-level episodes and was distributed via shareware and mail order. The Ultimate Doom, an updated release of the original game featuring a fourth episode, was released in 1995 and sold at retail.
Linux gaming
The beginning of Linux as a gaming platform for commercial video games is widely credited to have begun in 1994 when Dave D. Taylor ported the game "Doom" to Linux, as well as many other systems, during his spare time. From there he would also help found the development studio "Crack dot Com", which released the video game" Abuse", with the game's Linux port even being published by Linux vendor Red Hat. id Software, the original developers of "Doom", also continued to release their products for Linux. Their game "Quake" was ported to Linux in 1996, once again by Dave D. Taylor working in his free time. Later id products continued to be ported by David Kirsch and Timothee Besset, a practice that continued until the studio's acquisition by ZeniMax Media in 2009. In 1991 DUX Software contracted Don Hopkins to port "SimCity" to Unix, which he later ported to Linux and eventually released as open source for the OLPC XO Laptop. Other early commercial Linux games included "Hopkins FBI", an adventure game released in 1998 by MP Entertainment, and "Inner Worlds" in 1996, which was released for and developed on Linux. In 1998, two programmers from Origin ported "Ultima Online" to Linux. A website called The Linux Game Tome began to catalog games created for or ported to Linux in 1995.
