The study aims to highlight the issue of “reality” within the Simulation and Gaming (S&G) domain, which has been largely overlooked. The research community has struggled to connect game experiences to realities, especially from the perspectives of game designers and facilitators. Awareness of differing perceptions of reality has grown significantly, driven in part by the rapid spread of misinformation and conspiracy theories on social media. Consequently, the realities perceived by players may differ from those intended to be shared by game designers and facilitators. However, this awareness within the S&G community is insufficient. To address this, the authors explore the issue theoretically. First, the importance of increasing awareness is explained using various concrete examples. Second, the role of facilitators, who play an essential role in the S&G process, is explored. Third, insights are derived from foundational research in this field, offering various perspectives to address the issue. Lastly, the authors emphasize the need for actively discussing the issue of realities in the S&G community and reiterate the associated risks.
