Clausewitz Engine

In 2007 the Paradox Development Studio debuted a proprietary game engine, titled Clausewitz (named after the Prussian general Carl von Clausewitz), in Europa Universalis III which has been put to use in every game developed by PDS since. The engine provides a 3D view of part or the totality of the world map, depending on the played game. Sengoku was the first game utilizing the Clausewitz 2.5 engine.
