The need to play is primeval in human beings, at least as strong as the urge to fight. While the larger gaming community has traditionally focused on the fairly lucrative potential of exploiting the urge to fight in the form of violent and destructive war games, the "Serious Games" segment has become aware of the power of applying this technology "beyond entertainment" to advance social good. So far most of this work has focused on the areas of civics, health, education and NGO policy advocacy. Relatively little has been explored in the crucial domain of conflict resolution, especially as it pertains to promoting positive social skills in childhood. The authors seek to address this important need by offering a first empirical analysis of the impact that can be had from a new digital game designed to teach conflict resolution to children: "Cool School: Where Peace Rules." This enjoyable interactive PC based game has already furnished visible and inspiring evidence of just how games can help children learn not to fight, but rather to negotiate, compromise and consider other perspectives, even at an early age. They hope to inspire further research and reflection in this area, as well as wider distribution of this particular new game.
