Crusader Kings is a grand strategy game developed by Paradox Development Studio and published by Paradox Interactive in 2004. It is set in the time-period from December 26, 1066 until December 30, 1452. Unlike past Paradox titles (Hearts of Iron, Victoria: An Empire Under the Sun and the Europa Universalis series), Crusader Kings focuses on building a dynasty instead of a country, having similarities to role-playing video games. The lead game programmer was Johan Andersson. As with the other Paradox Interactive history games, Crusader Kings is considered a macro-management real-time strategy game (as moves are played out simultaneously and continuously) but typically involves far more planning than the fast-paced action that is usually associated with real-time strategy.
