Space Quest 4 was released on floppy disks on March 4th, 1991, and in December 1992 on CD-ROM with full speech support, with Laugh-In announcer Gary Owens as the voice of the narrator. Using the SCI engine, it featured 256 colors, hand painted graphics, and a full, mouse-driven interface. It was one of the first-ever games to use motion capture animation. The game cost over $1,000,000 US to produce, but sold more than its three predecessors combined.
