The Avalon Hill Diplomacy cooperative board game is a game of negotiation, cunning, and deceit. Through making deals and forming alliances, you'll expand your empire over pre-World War I Europe. You'll have to watch your back as you make and break deals, un-hatch traitorous plots, negotiate, and outwit others to gain dominance of the continent. It's a strategy game in which players must rely on their own cunning and cleverness, not the luck of the dice, to determine the outcome. It's a great choice for those who love multi-player strategy games, European political games, and cooperative board games. For 2-7 players, ages 12 and up, and can take about 6 hours to play.
