Unreal Engine 1

Meta article
The following is a meta-article, which explains a concept which usually falls out of one of the wiki's categorizations, yet it's still important to explain something.

The Unreal Engine 1 is the first generation of the Unreal Engine game engine family.

Overview

Making its debut in 1998, the first generation Unreal Engine integrated rendering, collision detection, AI, visibility, networking and file system management into one complete engine. With the level of integration used, some trade-offs were necessary to maintain performance levels with the hardware that was available at the time. For example, Epic decided to use cylindrical collision detection over the IK collision detection system in an effort to maintain playable framerates on systems that were common at the time of its release. Internally, Epic used this engine for Unreal and Unreal Tournament.

In 2015 Tim Sweeney told in an interview that he hoped to one day be able to release the engine as open source to the public.
