Title: Unreal (1998 video game)
Content:  While many game companies went from FM synthesis or General MIDI in the early 1990s to enhanced CD audio and pre-rendered audio, many of the Epic Games used the less common system of module music, composed with a tracker, which used stored PCM sound samples of musical instruments sequenced together to produce music. Epic had been using this technology for other games such as Jazz Jackrabbit and One Must Fall: 2097, which allowed relatively rich music to be stored in files usually smaller than one megabyte. This technology allowed easy implementation of dynamic music for mood changes in Unreal. The Unreal soundtrack was written by MOD music authors Alexander Brandon and Michiel van den Bos with a few selected tracks by Dan Gardopée and Andrew Sega. Unreals music engine also supports CD audio tracks. The game also made use of the Aureal 3D technology.

Title: Unreal Tournament
Content:   Lead designer Cliff Bleszinski credited much of the game's success to its community. As he said in the November 2001 issue of Maximum PC, "Unreal Tournament would not have sold nearly two million copies if it did not have support from the community... We ship the very same tools that we used to build the game, and folks use these tools to realize their own visions of first-person action". Like Unreal, Unreal Tournament is designed to be easily programmable and highly modularized. Through its scripting environment UnrealScript and level editor UnrealEd, developers are able to modify easily most parts of the game to both manipulate default game behavior and to supplement the game with their own mods. These range from slight changes on some aspects of gameplay (such as map voting) to total conversions. One modification, ChaosUT, became popular enough that it was included with the 'Game of the Year' edition of the game, while Tactical Ops: Assault on Terror was released as a stand-alone retail product. Unreal Tournament was played at the World Cyber Games in 2001 and 2002.
