QuakeSpasm is a modern, cross-platform Quake 1 engine based on FitzQuake.

It includes support for 64 bit CPUs and custom music playback, a new sound driver, some graphical niceities, and numerous bug-fixes and other improvements.

Quakespasm utilizes either the SDL or SDL2 frameworks, so choose which one works best for you. SDL is probably less buggy, but SDL2 has nicer features and smoother mouse input - though no CD support.

id Software created Quake in 1996, and released the source code to the engine (under the GPL licence) in 1999. Tonik developed the ZQuake QuakeWorld client from this, before fuh took ZQuake and turned it into FuhQuake.

The ezQuake project started in August 2004 as a derivative of FuhQuake, and today is the dominant QuakeWorld client for those playing online competitively.

Lee Vermeulen, the Nexuiz project founder, decided to license the Nexuiz code to a new game development company named Illfonic so that they could develop a closed-source version for the PS3.

The hijacking of the Nexuiz project by its absentee founder and IllFonic made it clear that it had no future as it stood and thus the community left to found Xonotic.

An addictive, arena-style first person shooter with crisp movement and a wide array of weapons, uses DarkPlaces game engine.

Xonotic is and will always be free-to-play. It is available under the copyleft-style GPLv2 license.
