Funded by the Vielberth Foundation and sponsored by the Leibniz Institute for East and Southeast European Studies and the Department of Interdisciplinary and Multiscalar Area Studies at the University of Regensburg, this two-day symposium analysed the dual role of computer games as transregional, nationalistic propaganda machines on the one hand and as democracy and diversity-fostering, critical and prosocial media experiences on the other. It explored how the social and political actions of players are shaped by nationalist or fascist content, how such content appears in games, and how, conversely, pro-democracy, sustainability-promoting elements can be incorporated, experienced and learned in and through the design of alternative “indie” games. Sonia Fizek gave a talk on “Materiality of Digitality. The Politics and Ethics of Making Videogames”. The topic corresponds to Games Infrastructures, one of the four themes covered within the Greening Games project.
