This document summarizes the insights from the evaluation and impact assessment across the different case studies in the GREAT project. It builds on the evaluation framework defined in Deliverable D5.1 and presents the findings along five impact dimensions: participants, scientific, economic, and societal. We clearly find impact traces across all four dimensions. Across the GREAT case studies there is strong evidence that game-based interventions can enhance climate awareness, support deliberative discussion, and generate valuable insights into public attitudes, emotions, and behaviours related to climate change.
