From October 17 to 25, 2018, the Library of humanities and social sciences of Université de Montréal is hosting an exhibition named Donjons & Données probantes («Evidence-Based Dungeons») on the academic research and tabletop role-playing games.
Designed by Sébastien Savard and me, this exhibition shows :

how the scientific studies answered the moral panic of the 80s ?
how the academic and para-academic researches reattributed the original authorship to the creation of tabletop roleplaying games ?
how and why the design of D&D evolved through the decades ?
what designed the Québec and Canadian publishers and authors ?
how the innovations in game design evolved from 1974 to 2018 ?
