DVD game

An interactive movie, also known as a movie game, is a video game that presents the gameplay in a cinematic, scripted manner, often through the use of full-motion video of either animated or live-action footage. In modern times, the term also refers to games that have a larger emphasis on story/presentation than on gameplay.

This genre came about with the invention of laserdiscs and laserdisc players, the first nonlinear or random access video play devices. The fact that a laserdisc player could jump to and play any chapter instantaneously (rather than proceed in a linear path from start to finish like videotape) meant that games with branching plotlines could be constructed from out-of-order video chapters in much the same way as Choose Your Own Adventure books could be constructed from out-of-order pages, or the way an interactive film is constructed by choosing from a web of linked narratives.

Thus, interactive movies were animated or filmed with real actors like movies (or in some later cases, rendered with 3D models), and followed a main storyline. Alternative scenes were filmed to be triggered after wrong (or alternate allowable) actions of the player (such as 'Game Over' scenes).

An early attempt to combine random access video with computer games was Rollercoaster, written in BASIC for the Apple II by David Lubar for David H. Ahl, editor of Creative Computing. This was a text adventure that could trigger a laserdisc player to play portions of the feature film Rollercoaster (1977). The program was conceived and written in 1981, and published in the January 1982 issue of Creative Computing, along with an article by Lubar detailing its creation, an article by Ahl claiming that Rollercoaster is the first video/computer game hybrid and proposing a theory of video/computer interactivity, and other articles reviewing hardware necessary to run the game and do further experiments.
