Paradox Interactive AB is a video game publisher based in Stockholm, Sweden. The company started out as the video game division of Target Games and then Paradox Entertainment before being spun out into an independent company in 2004. Through a combination of expanding internal studios, founding new studios and purchasing independent developers, the company has grown to comprise nine first-party development studios, including their flagship Paradox Development Studio, and acts as publisher for games from other developers. Paradox is best known for releasing strategy video games, especially historically-themed grand strategy games, and has published strategy games in different settings, as well as games of other genres such as role-playing video games and management simulators. They typically continue development of their games after initial release with the creation of downloadable content, and are also known for creating games that are easy to mod. Outside of video games, Paradox has created board games based on several of its titles, and owns the rights to the tabletop role-playing game series World of Darkness since purchasing White Wolf Publishing in 2015.
