The 7th Guest, produced by Trilobyte and released by Virgin Games in 1993, is an interactive movie puzzle adventure game. It was one of the first computer video games to 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 a great amount of press attention for making live action video clips a core part of its gameplay, for its unprecedented amount of pre-rendered 3D graphics, and for its adult content. In addition, the game was very successful, with over two million copies sold, and 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 7th Guest was the brainchild of game designer/graphic artist Rob Landeros, and a Virgin MasterTronics programmer, Graeme Devine. When Landeros and Devine presented their idea for the game, they were promptly "fired" so that they could start their own company, Trilobyte, dedicated solely to the development of this game. They originally intended to create the movements through the mansion using video. 3D graphics and animation were introduced to the title early in '91 when Robert Stein III joined the team.
Graeme Devine created the game's engine GROOVIE, which allowed continuous streaming of data from CD-ROM.
The game was to be ported to the unreleased SNES-CD peripheral.
In December 2010 the game was relaunched for iOS, for iPhones and iPads.
On the 13th of March 2012, Trilobyte released the game for Mac OS X on the App Store
