Amiga versionThe back cover of the Amiga version contains information: "Beautiful graphics in 256 colours or 32 colours (two versions available)." but the game was released only in 32 colours version.
According to KQ VI reviews in Amiga Computing, Amiga Format and Amiga Power magazines Sierra originally planned to release a 256 colours version but decided that 32 colours version looked so good already so they shelved the idea.
The game was ported to the Amiga by Revolution Software, though the company wasn't credited on the box or in the manual. This is why this version uses Revolution's Virtual Theatre engine instead of SCI.
CD versionThe CD version of King's Quest VI includes Girl in the Tower , the theme song to the game, composed by Mark Seibertm in full length. A sample of it can be heard on the floppy version for five seconds, then the game urges you to ring up radio stations that was listed in the manual and request it. Also the introduction was also extended in the CD version.
MusicChris Braymen, the game's composer, quoted a Gregorian chant (Dies Irae) in the theme that plays when Prince Alexander is captured in the Catacombs of the Isle of the Sacred Mountain. It's a famous theme, quoted as well in many classical compositions such as Berlioz' Symphonie fantastique (5th part), in Stanley Kubrick's films The Shining and A Clockwork Orange, and also in Indiana Jones and the Fate of Atlantis (Room of the God Machine).
ReferencesKing's Quest VI's villain is named Abdul Alhazred; this name was taken from the work of horror and sci-fi writer H.P. Lovecraft. Abdul was a fictional character (also dubbed ''the Mad Arab'') who wrote the Necronomicon.
TechnologyThis was Sierra's first adventure game to feature their lipsyncing technology that they got when they bought out Bright Star Technology.
