Crusader Kings Games
Crusader Kings is Paradox Interactive's medieval grand strategy series, and it's about people more than armies. You play a dynasty instead of a nation, managing marriages, rivalries, faith, and ambition across generations, and the best stories tend to come from things going wrong: a scheming brother, a bitter succession, an heir you never planned for. The series has three main games, and each has a large library of expansions and packs that add new cultures, mechanics, and regions.
Crusader Kings III
Crusader Kings III, released on September 1, 2020, is the newest game and the easiest place to start. GameBoost carries the Crusader Kings III base game for PC, plus an Xbox Series X|S version, and two bundled editions. The Starter Edition adds one major expansion, one event pack, and some cosmetics to the base game. The Royal Edition bundles the base game with the Expansion Pass, which covers the first wave of content, including Royal Court, Northern Lords, and Fate of Iberia.
Crusader Kings III Expansions and DLC
Paradox releases CK3 content in tiers. Royal Court, Roads to Power, and All Under Heaven are major expansions, while Legends of the Dead, Khans of the Steppe, and By God Alone are core expansions that focus on one system, such as the nomadic government in Khans of the Steppe and religious life in By God Alone. Smaller packs, including Fate of Iberia, Northern Lords, Tours & Tournaments, Friends & Foes, Legacy of Persia, Wards & Wardens, Wandering Nobles, and Coronations, add narrower content, and the Content Creator Packs are cosmetic clothing and monument packs. Chapter passes bundle several releases together. Chapter IV covers Khans of the Steppe, All Under Heaven, Coronations, and a cosmetic crown pack. Chapter V includes By God Alone, a music pack, a cosmetic pack, and the major expansion Silk & Silver, which Paradox has scheduled for Q4 2026.
Crusader Kings II
Crusader Kings II, released in 2012, made the series' name. It has a more traditional, menu-driven interface and an enormous expansion library built up over several years, and it still has a loyal following for its depth and mods. GameBoost carries the base game and three collections: the Collection (2014), the Royal Collection, and the Imperial Collection, with the Imperial Collection the largest of the three.
Crusader Kings II Expansions and DLC
The fifteen expansions change how the game plays. The Old Gods adds a 867 start date and the pagan Viking age, and Charlemagne adds an earlier 769 start. Sons of Abraham and Sword of Islam deepen the Jewish and Muslim faiths, Legacy of Rome centres on Byzantium, and The Republic adds merchant republics. Rajas of India and Jade Dragon extend play eastward, Horse Lords brings nomadic invaders, and The Reaper's Due adds plague and death. Way of Life, Conclave, Monks & Mystics, Holy Fury, and Sunset Invasion round out the list. Beyond the expansions, there are content packs such as Ruler Designer and the Customization Pack, unit packs and portrait packs that change how armies and characters look, nine music packs, and the Ultimate Unit, Portrait, and Music collections that bundle each group. The Song of Roland and Tales of Treachery ebooks and the Europa Universalis IV Converter are also available.
