There are seven games that I know of that can be run stand-alone on an Amiga using the Quake engine (Most so called Total Conversions can't).
4D Shooter
Multiplayer only, and only to be found in an obscure section of GameFront.com. Can still be found on Arc.org.

Transfusion (old version)
Fails the registered Quake check, but borrowing gfx/pop.lmp from OpenQuartz solves that.
http://sourceforge.net/projects/bloo...ansfusion/1.0/
Update
http://sourceforge.net/projects/bloo...nsfusion/1.01/
Several of them borrow parts from OpenQuartz but they do not use the entire ID1 drawer, unlike Half-Life/Turok/Left4Quake e.t.c.
If anyone knows of any more please let me know. Will update this with a lot more detail later... maybe.
