The Groovie engine was used to create several games between 1993 and 1998. It was originally developed to use the full potential of the then emerging CD-ROM, and it can be considered a video player with interactive parts. There are two main versions of the engine: the first version (just used in The 7th Guest) plays VDX videos using 256 colors, while the second version (used from The 11th Hour on) requires 16bpp to play ROQ videos (a format which was later also used in id Software's Quake 3).

Games
