Europa Universalis IV

The game is mainly set in the historical era of the initial European exploration and colonization of the New World. The game map covers the entire Earth (minus the polar regions), and players are free to explore and expand into most of it except for certain lands such as deserts and tundra that are considered uninhabitable or unexplored historically during the in-game years. Players can choose to play single-player mode versus the AI, or multiplayer over a LAN or the Internet against a mix of human and AI opponents. The player may also switch to controlling a different country within the same game world.
