Banned in Australia for containing a demo of Roberta Williams' Phantasmagoria.
Although most of the games included have a very friendly theme and setting, this compilation still got a USK "nicht geeignet unter 18 Jahren" rating in Germany because the first chapter of the horror game Phantasmagoria was included as a bonus. They banned the full version of the game.
Dark Crystal was a last-minute addition to the package (probably due to Sierra needing to negotiate for the rights to include it) and is not mentioned on the cover.
This collection was taken out of print and replaced with the King's Quest Collection, which contains many of the games listed above.
