Players create maps for various different media. These “Choose Your Own Adventure” books, which were especially popular in the 1980s, combined aspects from games and adventure novels. The story advanced according to the choices made by the player. In order to make sense of their adventure, the unknown player of this Varkaiden kaupunki (“City of Thieves”) adventure book found from a flea market has drawn a map while reading. A storage pocket for the map has also been made on the book cover.
