  Tabletop fantasy role-playing games (TFRPGs) have existed in offline and
online contexts for many decades, yet are rarely featured in scientific
literature. This paper presents a case study where TFRPGs were used to generate
and collect data for maps of belief environments using fiction co-created by
multiple small groups of online tabletop gamers. The affordances of TFRPGs
allowed us to collect repeatable, targeted data in online field conditions.
These data not only included terms that allowed us to build our maps, but also
to explore nuanced ethical problems from a situated, collaborative perspective.
