id Software was an early pioneer in the Linux gaming market, and id Software's Linux games have been some of the most popular of the platform. Many id Software games won the Readers' and Editors' Choice awards of Linux Journal. Some id Software titles ported to Linux are "Doom" (the first id Software game to be ported), "Quake", "Quake II", "Quake III Arena", "Return to Castle Wolfenstein", ', "Doom 3", "Quake 4", and '. Since id Software and some of its licensees released the source code for some of their previous games, several games which were not ported (such as "Wolfenstein 3D", "Spear of Destiny", "Heretic", "", "Hexen II", and "Strife") can run on Linux and other operating systems natively through the use of source ports. "Quake Live" also launched with Linux support, although this, alongside OS X support, was later removed when changed to a standalone title.
