”Europa Universalis IV gives you control of a nation to guide it through the years and create a dominant global empire in the age of exploration, providing unprecedented freedom through the use of exploration, trade, warfare and diplomacy to let you rule your nation however you see fit. Strategists will face ruthless AI in an extensive single-player campaign, or be able to backstab friends and foes in 32-player online matches,” blurbs Paradox.
