The expansion Napoleon's Ambition extends the end game year forward to 1821, whereas the expansion In Nomine moves the starting year back to 1399, making it the longest as far as gameplay time in the series thus far.Įuropa Universalis III was the first to use Paradox's new 3D engine, Clausewitz Engine, that required user systems to meet the Pixel Shader 2.0 specification. The original game without expansions starts in 1453, right after the Fall of Constantinople, and continues to 1789, just past the beginning of the French Revolution. The player controls a nation and handles matters concerning war, diplomacy, trade, and economy. The game was released for Microsoft Windows in January 2007, and was later ported to OS X by Virtual Programming in November 2007. Europa Universalis III is a grand strategy video game developed by Paradox Development Studio and published by Paradox Interactive.
