What obstacles for game designers arise from the tension between gathering data from citizens and addressing a non-digital but spatially defined audience? This question arose during the Games for Cities game jam held on the 22nd and 23rd of march at the Designhuis in Eindhoven. A collaboration between Games for Cities, Het Nieuwe Instituut through the DATAstudio, the Municipality of Eindhoven, and the Design Academy of Eindhoven offered three groups of design specialists, inhabitants, researchers, and others that would take on a design challenge offered by the municipality.
