Graal3D: Engine
From Graal Bible
Graal3D is the 3D version of GraalOnline, and it is being developed with the Torque game engine by Linux Cyberjoueurs.
The Graal3D engine is known to be nutoriously complex, but can be fully controlled by using clientside and Graal3D-specific script functions.
There are a number of Graal3D servers, none of which are available to average Graalians, such as Graal3D, Graal3D City, Mushia and Doomsday3D.
