DNF engine history

December 1996: 3D Realms, started the DNF project with id Software's "QUAKE 1" engine instead thier own PREY engine.
April 1997: upgraded to id Software's "QUAKE 2" engine.
May 1998: Released on QUAKE 2 engine based DNF at E3.
June 1998: changed to Epic Games's "UNREAL" engine.
Decembner 1999: upgraded to the Epic Games's "UNREAL TOURNAMENT" engine.
January 2001: switched editor to "UnrealEd 2.0" instead "UnrealEd 1.0"
June 2001: Released on "UNREAL ENGINE 1 build 613" based DNF at E3.
August 2001: they taken some "Unreal Warfare" engine stuff such as "STATIC MESHES(HARDWARE BRUSH)" and they have written a tremendous amount of their "own rendering" system.
August 2002: included MathEngine's "KARMA" physics engine.
September 2004: changed physics engine to Meqon Research AB's "MEQON" physics engine instead KARMA Physics Engine.

Finally DNF engine Spec

based on heavily modified Unreal Engine 1 core system framework
uses a Unreal Engine 1 based UnrealScript Programming Language
Unreal Engine 1 based Network Engine
heavily modified UnrealEd 2.0 called the DukeEd (Duke Enormous Tool)
included some Unreal Engine 2 stuff such as Static Meshes
3D Realms own Rendering engine such as Fully Real-Time Lighting, Shaders, Post-Processing Efeects.
Meqon Physics Engine

Non-gaming Projects

Unreal Engine 1 is used in some non-gaming projects including construction simulation and design, training simulation, driving simulation, virtual reality shopping malls, movie storyboards, continuity, pre-visual, etc.

Discussion

Xian: So from what I understand, UE1 officially stopped at build 613 (used for licenses) which include a prototype version of what UE2 features, am I correct ?

El Muerte: no, there is no official "end" of UE1 or "begin" of UE2.

Xian: I see. So all those "new" features are things each developer added by themselves?

El Muerte: yes and no, in quite some cases licensees added features, but it also happens a lot that they backport features of newer versions of the engine, rather than completely upgrading to the newer version of the engine. For example, if you're using version 600 and have most of it nailed down and stable, you don't want to migrate to version 700 just for one new feature. You would backport it to version 600. It's much less work. You should take the engine version information about 3rd party titles with a grain of salt.
