Loki Software, although a commercial failure, is credited with the birth of the modern Linux game industry. Loki developed several free software tools, such as the Loki installer (also known as Loki Setup), and supported the development of the Simple DirectMedia Layer. They also started the OpenAL audio library project (now being run by Creative Technology and Apple Inc.) and with id Software wrote GtkRadiant. These are still often credited as being the cornerstones of Linux game development. They also worked on and extended several already developed tools, such as GCC and GDB. The book "Programming Linux Games" written in the early 2000s by Loki intern John R. Hall explains the major APIs Loki used to produce Linux games.
