Gameplay
Each player is controlled by either a human or by the computer; recent versions of the game have included the option of network play. At the beginning of the game, the players choose a unique political ideology, select or are assigned a flag and a home country, and are given the same number of armies. Each country on the map is assigned a political ideology. Players then take turns during which they attack neighbouring countries and, if successful, occupy them with some of their armies. If the occupied country's political ideology matches that of the player, then only one occupying army is required; otherwise, the game informs the player how many more occupying armies are required. If the player fails to maintain the minimum number of occupying armies in a country, the country may revolt and switch allegiances to another player. A player can end his turn at any time, and usually does so when he has no further armies with which to attack. At the beginning of each turn other than the first, the player receives a number of armies calculated from the number of countries he holds, plus a bonus if he controls entire continents.
The game ends once one player has occupied all his opponents' countries, or when all his opponents have surrendered.
