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[42] and was one of Infocom's most successful games.[43] 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).[44]
