This workshop brings together two key topics in their respective global research fields: intelligent agents and serious game design. Both are proving more important every year as means of engaging large audiences with new ways of thinking about social interaction, entertainment, culture, social policy, the environment and the way we work and learn. Bringing together the concepts, technologies, and methodologies of the two fields holds the potential to allow their combined strengths to further drive engagement, communication, and understanding between innumerable groups around the world.
