id Tech 1
The Doom engine was the engine developed by id Software that powered the 1993 mega-hit Doom, succeeding the Wolfenstein 3D engine and preceding the Quake engine. It was later re-christened id Tech 1 as part of the id Tech family of game engines. Its breakthrough graphics were made possible through its innovative use of binary space partitioning. The modern GZDoom engine has been used in recent times in a number of indie games. The Doom engine code was released in 1997, with the Raven Software games code released in 1999, and even several of the console versions seeing eventual source releases. Strife and Doom 64 were later reverse engineered, with the highly modified Killing Time still closed source.

A Chex Quest 3 was released in 2008, supplanting a controversial unofficial pretender from 1996. Original designer John Romero has continued the classic games with the Sigil series, while later re-releases of the game have featured new expansions such as No Rest for the Living, The Lost Levels, and Legacy of Rust. The engine behind Alien Cabal is highly similar, but not directly derived, while the engine for Mars 3D was reverse engineered.
