La Aventura Colosal is a book written by Jesús Martínez del Vas and published by Dolmen Editorial that tells the history of conversational adventures (or interactive fiction) from its beginnings with Adventure and Zork, to the present day. The book covers in detail the founding of Infocom, the ins and outs of famous adventures such as The Hobbit, and delves into the trajectory of Level 9, Magnetic Scrolls or CRL. The book also talks about adventure creation tools or "parsers" and, of course, about the important history of conversational adventures in Spain, from Dinamic's Yenght to the end of Aventuras AD.
