The implementation of the german energy transition (Energiewende) is unclear in its configuration and timeframe. The future of the transition depends on more than factors such as technological development, economic feasibility and political framing. Rather, maintaining a positive attitude by society and its understanding is significant. Therefore, effectively communicating the complex process of energy transition is essential. For preserving the variety of aspects and the multitude of perspectives in this open process we choose the format of a serious game. We explain why we think developing serious games can be an appropriate tool for that purpose. Contrary to existing games on that topic, we focused on motives, attitudes and their implications in a world full of contradictions and caprices in everyday life. We created an innovative adventure, which focusses on the energy transition. This topic represents a challenge because it bears complex interrelations (technical, political, social) and strong polarization in debate. In order to achieve a compelling game experience as well as a learning outcome, we use a set of characters to represent different attitudes. While dealing with job-related and day-to-day tasks, the characters run into the dilemma of foiling their commitment to sustainability. In the quest of a balance between consumption and happiness, they have to make energy-aware decisions and cooperate with each other.
