The 7th Guest

The 7th Guest is a 1993 interactive movie puzzle adventure game developed by Trilobyte and published by Virgin Interactive Entertainment for DOS. It is one of the first computer video games to initially be released only on CD-ROM. The 7th Guest is a horror story told from the unfolding perspective of the player, as an amnesiac. The game received press attention for making live-action video clips a core part of its gameplay, as well as for its unprecedented amount of pre-rendered 3D graphics and its adult content.

The game was critically and commercially successful, selling over two million copies. Alongside Myst, it is widely regarded as a killer app that accelerated the sales of CD-ROM drives. Bill Gates called The 7th Guest "the new standard in interactive entertainment". The game has since been ported in various formats on different systems.
