Video Games Encyclopedia

Some adventure games have been presented as interactive films; these are games where most of the graphics are either fully pre-rendered or use full motion video from live actors on a set, stored on a media that allows fast random access such as laserdisc or CD-ROM. The arcade versions of Dragon’s Lair and Space Ace are canonical examples of such works. The game’s software presented a scene, to which players responded by moving a joystick and pressing a button, and each choice prompted the game to play a new scene. The video may be augmented by additional computer graphics; Under a Killing Moon used a combination of full-motion video and 3D graphics. Because these games are limited by what has been pre-rendered or recorded, player interactivity is limited in these titles, and wrong choices or decisions may lead quickly to an ending scene.
