=================================================
Sometime between 1982 and 1984 (accounts differ) the British company Supersoft published a text-based adventure game based on the book, which was released in versions for the Commodore PET and Commodore 64. One account states that there was a dispute as to whether valid permission for publication had been granted, and following legal action the game was withdrawn and all remaining copies were destroyed. Another account states that the programmer, Bob Chappell, rewrote the game to remove all Hitchhiker's references, and republished it as "Cosmic Capers".[32]
=================================================

Officially, the TV series was followed in 1984 by a best-selling "interactive fiction", or text-based adventure game, distributed by Infocom. It was designed by Adams and Infocom regular Steve Meretzky and was one of Infocom's most successful games. As with many Infocom games, the box contained a number of "feelies" including a "Don't panic" badge, some "pocket fluff", a pair of peril-sensitive sunglasses, an order for the destruction of the Earth, a small, clear plastic bag containing "a microscopic battle fleet" and an order for the destruction of Arthur Dent's house (signed by Adams and Meretzky).
