In response to the global climate crisis, scalable and engaging methods to reach diverse citizens are urgently needed. Game-based approaches have become increasingly popular for promoting climate change engagement across cognitive, affective, and behavioural dimensions. However, they often face implementation challenges related to recruiting participants, long duration, and equipment. An underexplored avenue is the use of existing public or commercial video games with environmental or climate themes - so-called green games - to promote engagement. This study addresses this gap by exploring the prevalence of green gaming and its potential impact on climate change engagement to identify potential applications and avenues for game-based interventions. We conducted an exploratory online survey distributed in video gaming communities across the globe (n = ~15,000), combining quantitative items with an open-ended question analysed using qualitative content analysis. Preliminary results highlight key motivations, emotions, and behaviours linked to playing green games, with variations across geographic regions, sociodemographic groups, and game titles. Furthermore, early qualitative insights provide a deeper understanding of players' experiences with green games and how they relate to topics like climate change and biodiversity. Notably, themes of climate scepticism and distrust toward political and societal actors emerged as influential factors within gaming communities' engagement with these topics. These findings offer novel insights into the expanding gamer population's interaction with environmentally themed games and their potential role in promoting climate change awareness and action. The study also highlights limitations and barriers to using video games as tools for climate engagement. Additionally, this research positions video games as a viable tool for applied psychology, allowing to access diverse populations and opening promising avenues for interdisciplinary research and practical applications.
