From a definition, based upon the media ecology, of role- playing game (RPG) as a media with narrative language, printed technology and an interactive form of reception, it is proposed that this game can be though as a narrative hypermedia with its componentes acting as links to other informations, promoting a creative reality refiguration. A proposition is presented for a method of poetic conception and crytical analysis for an object of graphic design, a RPG book, in in which the concept of text opening is fundamented on the concepts of text enjoyment, Roland Barthes' sign sliding and unlimited semiosis of C.S. Peirce, worked through the intersemiotic translation of Julio Plaza, Paul Ricoeur's hermeneutic and Erwin Panofsky's iconology. It is hoped that this method will contribute not only with new possibilities for book conception and production, but also with the assembling and questioning of an epistemology for the Design as an area of knowledge. This discussion is done in two instances: a formal instance, where the conception of the printed support for the Barroque Brasil setting is documented, for the experimental RPG Incorporals, developed alongside the method; and a processual instance, where the support of this rpg will be experimented by players that will participate in the setting development through the production of materials that will be incorporated in the printed supports, verifying the capacity for the openings described above.
