This study investigates the game mechanics necessary to induce real-world climate action by adopting a theoretically well-known model of collective action called the Wilcox Ladder of Participation to create a “Games Ladder for Climate Action.” We then evaluate 10 games based on the different levels in the ladder, which includes the ability to inform, consult, involve players in decision making, facilitate collaborative actions, and inspire real-world independent actions. The results show that many games are effective in educating players, but fail to foster deeper engagement mechanisms such as player feedback, decision-making involvement, and collaborative problem solving, which are necessary for promoting real action. This study offers a framework that game developers can use to evaluate their games and some critical insights to help developers design more impactful educational games that not only inform, but also drive real-world action in response to environmental issues.
