This work documents an experiment in which Role Playing Games were part of the curriculum in a private school in Rio de Janeiro. The game was used as a tool to promote expression and creativity among the students and also the development of several competencies inside the classroom. Sixty-nine children and adolescents (ages 9 to 17, from the 5th to the 10th grade) took part in the workshops studied here. The filedwork methodology included observation, supported by field notes and photos, along with the analysis of artifacts produced by the students during (and for) the game sessions, such as character profiles, stories, assorted texts, drawings, maps, schetches, mock ups and others, and also their engajement in the preparation of a show, visited by parents, teachers, family membres and other members of the school community. As with theater, music, dace, video-production, animation and other forms of artistic and cultural expression, games like RPGs, that unite creativity and fun, might serve as a way to straighten the ties between the school and the complex, multiple and multimidiatic world where children and adolescents in major cities are imersed in day-to-day basis.
