The Hitchhiker's Guide to the Galaxy computer game was a text driven adventure with no graphic content that loosely followed the storyline of the first novel. It is in the same style as the first Zork computer game was played. The player assumes the role of Arthur Dent (at first), finding themselves at home on the morning that their house is to be demolished.
It came with a number of fantastic feelies, including carboard "peril-sensotive sunglasses," a plastic baggie labelled "Microscopic Space Fleet," pocket fluff, an "Order for Destruction" of Arthur Dent's house,and an alien-language "Order for Destruction" of Earth.
