PeaceMaker is a video game developed by ImpactGames, and published in February 2007 for Windows, Mac OS and Android. It is a government simulation game which simulates the Israeli–Palestinian conflict. Labelled as a serious game, it is often pitched as "a video game to promote peace". The game was originally a university project started in 2005 by a small team from the Carnegie Mellon University. After graduating, two of the members founded a game development company in order to finish the project.
