The game is a dynastysimulator in which the player controls a medieval dynasty from 1066 to 1453. Players are able to start at any date between September 15, 1066, to December 31, 1337.[a] Through the strategic use of war, marriages and assassinations, among many other things, the players work to achieve success for their dynasty.
Success is defined solely by the player. The only in-game objective is to obtain as many prestige and piety points as possible in order to surpass the various historically relevant European dynasties in a fictional prestige ranking system (the three most prestigious ones being the Capetian, the Rurikid and the Habsburg dynasties). The game ends when the player's current character dies without an heir of the same dynasty to succeed him/her, when all landed titles of the count rank or above are stripped from all members of the player's dynasty (including themselves), or when the game reaches its end in 1453 (unless the player is in "observer mode", at which point the game will continue onwards).
The game employs a genetics and education system, through which children inherit many traits, culture, religion and skills from their parents and guardians. This adds an additional layer of strategy to marriages, such that a player will attempt not only to form beneficial alliances, but also to select marriage partners with strong heritable traits to maximise the quality of offspring and thus strengthen the dynasty. This requires balancing sometimes conflicting interests; for example, while one possible marriage might allow some desirable alliance to be formed with another ruler, it may also require marrying a spouse with some undesirable traits. Such a trade-off can occur in the reverse as well: one possible spouse could possess highly desirable traits but yield no new alliances for the player's dynasty.[4]
Sword of Islam allows the player to play as most Muslim rulers. Focuses on making Sunni and Shia characters unique to play as with a new UI, story events, traits, government types and decisions. The game map was expanded into the Mali region.[5]
Legacy of Rome focuses on the Byzantine Empire, adding new events and game mechanics. It also adds the "Retinue" mechanic, allowing the player to maintain a standing army.[6]
Sunset Invasion's main focus revolves around a story event in which Europe is invaded by a fictional, more technologically advanced version of the Aztecs. They can appear later in the game and have a new religion and culture unique to them.[7]

Mods
Aside from the official expansion packs, third-party mods are available on sites such as the Steam Workshop.[21]
When a Crusader Kings II (CK2) game is launched, Paradox servers collect information about the game setup such as game version, single player or multiplayer, and what mods are in use.[22] Data collected on 23 April 2017 showed that at least 42% of users on that day had activated at least one mod.[22] Data also reveals that multiplayer "cheat mods" are popular, too, as are graphics or GUI mods.
A few accuracy and realism mods have also been produced by fans, such as Historical Immersion Project and CK2+.[23] A large number of total conversion mods are also available:
After the End, which is set in the 27th century in a post-apocalyptic North America, the most up-to-date version of the mod however goes by the name After the End Fan Fork.[27]
Paradox actively encourages modding, and the developers regularly tweaked the game in order to make modding easier, furthermore there exist in-depth guides on how to mod in the Crusader Kings II wiki.[22]
A demo was released on February 4, 2012, which featured four playable characters over a 20-year span.[37] A marketing campaign for the game featured light comedy videos on the concept of the Seven Deadly Sins.[38]
The game, based on the Clausewitz Engine, was met with generally positive reviews and has attained a metascore of 82 at Metacritic.[39]GameSpot reviewer Shaun McInnis stated: "Through a complex system of diplomacy and backstabbing, Crusader Kings II makes every power struggle an engrossing one" and he lauded the gameplay while noting the "lackluster tutorials".[34]IGN summed up their review by saying "an intense learning curve, but a unique strategy experience".[35] IGN rated the gameplay and "lasting appeal" a 9/10.[35] A reviewer for Rock, Paper, Shotgun wrote that Crusader Kings II was "probably the most human strategy game" he ever played.[40] Rob Zacny of PC PowerPlay, who gave the game a 7/10 score, called it a "brilliant treatment of feudalism in terms of strategy and story" but also stated it "requires major investment to overcome information overload".[36]Kotaku named the game as one of their game of the year nominees.[41]
By September 2014, Crusader Kings II had sold more than 1 million copies, with the expansion pack and DLC sales totaling over 7 million units. This makes it Paradox's most successful release prior to the debut of Europa Universalis IV.[42] According to Paradox Interactive, the game was played by an average of 12,500 players every day, with an average playtime of 99 hours per player.[43]
^Adam Smith (2012-02-23). "Wot I Think: Crusader Kings II". Rock Paper Shotgun. Retrieved 2013-02-02. When the consequences are so human they mean all the much more and this is probably the most human strategy game I've ever played. If it doesn't wind up being among my very favourite games of the year, spectacular things will occur in the next ten months.
