Stolen from Quakesrc.org
"JoeQuake is an improved NQ (Normal Quake, NetQuake or whatever you call, the main thing is that it's NOT QuakeWorld) engine with lots of ZQuake and FuhQuake graphical effects and also some of my own additions included. My main destination was to make demo watching the most comfortable, but it's also pleasant for playing. See more in the documentation with the zip, Download JoeQuake v0.13, which is still a BETA"
