WAW: War Across the World is an abstract strategy game that aims to simulate all wars and conflicts across the world.

From the Prehistoric Times to the Present Day, from grand massive wars to smaller wars and conflicts.

The main game screen displays a map of the world, in which are shown various countries and their respective flags. On the map, there are also shown the positions of military units, with the game recording the moves of the players. The players take turns to place their military units on the map, controlling countries and territories, either collectively or one at a time.
