Avalon Hill's Diplomacy, a strategy game released in 1999 by MicroProse Software. The game was released for PC (Windows).

Avalon Hill's Diplomacy is a game set at the turn of the 19th and 20th centuries. Several European powers are fighting among themselves for domination. The armies of seven countries undertake hostilities against each other. Players' strategic moves push boundaries and change empires with a variety of maneuvers. Strategy is important in the game. You can make alliances, intrigue, negotiate. You can betray or outsmart your opponents. Cooperation and competition between the great powers are intertwined. It is important to achieve your goal, which is to gain domination on the Old Continent. Success does not depend on luck - it is cleverness, cunning and strategic thinking that counts. Creating alliances and betraying them for your own benefit is the basis of the game. In Diplomacy, emotions and friendships are relegated to the background - what counts is cold calculation and using enemies to strengthen your position. The same is followed by others, so you should limit your trust and not be sentimental.
