The Hitchhiker’s Guide to the Galaxy is an interactive fiction video game based on the comedic science fiction series of the same name. It was designed by series creator Douglas Adams and Infocom’s Steve Meretzky, and it was first released in 1984 for the Apple II, Mac, Commodore 64, CP/M, MS-DOS, Amiga, Atari 8-bit computers, and Atari ST. It is Infocom’s fourteenth game.
The game loosely mirrors a portion of the series‘ plot, representing most of the events in the first book. Arthur Dent wakes up one day to find his house about to be destroyed by a construction crew to make way for a new bypass. His friend Ford Prefect, who is secretly an extraterrestrial, helps to calm Arthur down and hitches them a ride on one of the ships in the approaching Vogon constructor fleet, moments before the fleet destroys the Earth to make way for a new hyperspace bypass.
