EQuake
From QWiki
eQuake was a QuakeWorld package aiming to be the only thing QuakeWorld players would need to download to play a relatively competitive game, and was released on the 30th of September 2003. Development of eQuake slowly reached its end in the summer of 2004, and after about 3 years of being THE QuakeWorld package, fQuake was released and replaced eQuake in the hearts of QuakeWorld players all over the world.
