Linux and DOOM (1993)
(lemmy.world)
From Wikipedia, the free encyclopedia
Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).
Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

John Carmack, author of the Doom engine, is a long time Linux user and for a while the policy was to open source the idTech engines once they had moved on.
However, Doom was hugely popular on its own before this, and was actually more pivotal for making Windows a gaming platform (over DOS).
The reason it runs everywhere is a combination of it's huge popularity, it's (now) open source and it's generally low system requirements.
