Dreamweb big box
The original game came packed with a booklet named Diary of a Mad man, written by Stephen Marley which has a far more layered and atmospheric 'prequel' story than the one in the game itself. The diary also supplies more background info on the main character (and served as a copy-protection method).
Dreamweb's musical score, composed by Matthew Seldon, is highly regarded; the DOS-only CD version had an extra audio track.
