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 was first released in 1984 for the Apple II, Macintosh,Commodore 64, CP/M, DOS, Amiga, Atari 8-bit and Atari ST. It is Infocom’s fourteenth game.
Sure, it’s not a game in the standard sense, but a precursor to today’s walking simulator “games” like Gone Home, except that the Infocom games made you actually read, think, and experiment, so absolutely nothing like today’s walking simulator “games”.
Also, don’t believe it when it says there’s an exit to port.
