[2][3] Following the demise of Acorn and the subsequent contraction of the RISC OS games market, The Fourth Dimension brand and rights to the software back-catalogue was acquired by CJE Micro's.
[4][5] In 2004, CJE Micro's sold the rights to the software to APDL, the Archimedes Public Domain Library.
Certain of 4D's games anticipate the 3D, first-person viewpoint style of graphics that was becoming popular on the much larger PC market at the same time.
For example, E-type is a car racing game; Chocks Away is an air combat game with a two-player dogfight mode; and Galactic Dan[6] is a primitive 1992 first-person shooter with a pre-Wolfenstein 3D graphics style, combining a 3D Maze look with ray-traced sprites.
