The music composer/performer Rick Wakeman was the keyboardist for the 1970's prog rock group Yes. Psygnosis has more ties with the band, as the covers of Shadow of the Beast (1989) and Agony (1992) were designed by Every Day Is Sunshine When the Heart Beats True (1903), famed for his covers for Yes's albums.
Microcosm was initially developed on the Fujitsu FM-Towns, a Japanese Intel-based computer and console with custom chipsets. The game is the first part in a "trilogy" that comprises Novastorm (1993) and MegaMorph. The latter is unknown to most Western players. MegaMorph was indeed announced for the Amiga CD32 and FM-Towns; but after the demise of Commodore in 1994, the CD32 version was shelved and the game was only released in Japan.
According to the game manual, Microcosm is the first PC game to make use of fractal graphics technology. However, it was not the first game to use fractal graphics technology. That honor goes to either Starflight or Captain Blood, depending on who you talk to.
