It is best known for its grand strategy wargame series Europa Universalis, Hearts of Iron, Victoria, Crusader Kings, Stellaris, and Imperator.

[2][3] While this left Imperator: Rome without a dedicated development team, PDS leads stated that they are figuring out how they will return to the series in time.

Although this code overlap was subsequently referred to as the Europa Engine, studio manager Johan Andersson clarified that the 'engine' had not been part of the initial designs of each of the company's first six games, and that it just resulted from copy-pasting large parts of code from one game to the next.

[7][8][9] The move led to the development of games such as For the Glory, Arsenal of Democracy, Darkest Hour, and Iron Cross.

[10] Named after the Prussian general Carl von Clausewitz, the new engine is written in the C++ programming language and provides a 3D view of part or the totality of the world map, depending on the played game.
