The potential of game-based experiential workshops to complement focus groups in identifying drivers/barriers to environmentally sustainable food systems was explored. Sixty adults from an Italian bio-district answered to a questionnaire; among them, nineteen and twenty-one people participated in a game-based experiential workshop and in a focus group, respectively. The experiential workshop involved games, image theater, and on-the-spot feedback. The body language recorded during the workshop captured information on the transparency of producers and on the oppression from public institutions as perceived by citizens. Experiential workshops may have advantages over focus groups in terms of diagnostic potential.
