Serious games and simulations have long been applied in a wide variety of contexts to engage stakeholders in planning and policy-making processes. Practical experience and empirical research on their use suggest that games and simulations can help to clarify issues, interests and potential solutions among groups; provide safe and inexpensive opportunities for experimentation; and foster collaboration and build relationships to solve problems. While we have decades of experience using serious games and simulations, the state-of-the-art continues to evolve. Key driving forces that provide opportunities and threats include rapidly evolving digital technologies, decreasing trust in traditional 'experts' and the data they present, and declining trust in government and willingness to invest in community efforts to tackle challenges. This BRT will explore how serious games and simulations are evolving to meet emerging challenges and capitalize on new opportunities.
