Simulations and games can offer valuable insight into the management of conflict and the achievement of peace. This special symposium issue of "Simulation & Gaming" examines several such approaches, used in both educational settings and to prepare practitioners to deal with the concrete challenges of peacebuilding. In the introduction, the authors offer some brief thoughts on the how and why of simulations and games-based approaches, scenario choices (abstract, fictional, and real world), intended audiences, and design approaches. They also address the question of how games might (or might not) contribute to policy making in this field. (Contains 1 table.)
