Maybe Aphex Twin ripped off Mark Morgan. Hmm?
As much as I love Mark Morgan and his wonderful soundtracks, Aphex Twin did not rip him off, it was the converse. Interplay sent him a disc of music to use as inspiration, some of which was from Aphex Twin's Selected Ambient Works II, which Mark clearly imitated. In Fallout 2, you can actually hear one of Aphex Twin's tracks in the game from Selected Ambient Works II, and one of the robots says, "Humanoid Must Not Escape," which is a track by Casutic WIndow, an alias of Aphex Twin.
Mark Morgan is great, but Aphex Twin is a legend.
