Tabletop role-playing games (TTRPGs) are increasingly used in therapeutic and educational settings to improve the well-being of autistic people. This study investigated the potential of TTRPGs to provide a safe space where autistic adults could develop relationships with others while also engaging in character and world-building. Eight autistic adults were split into two groups and taken through a 6-week online Dungeons and Dragons campaign run by one of the researchers. Semi-structured interviews were then conducted to discuss how participants felt interacting in and out of the TTRPG. Several key themes were identified as important aspects of why autistic people could benefit from role-playing environments. The analysis showed that the participants felt a strong level of enjoyment from engaging in tabletop role-playing and, in many ways, experienced better social interactions during the TTRPG. The results suggested that TTRPGs can provide a safe space for autistic adults to engage in meaningful social interactions with like-minded individuals. Role-playing may also allow autistic participants to rewrite their own life stories through their characters' adventures, leading to improved self-esteem.
