With the release of Crusader Kings III imminent, I wanted to revisit Crusader Kings II, and touch on why I consider it the most significant strategy game of the last decade. While other games (XCOM, FTL) were more influential, I would argue it was CK2 that pushed the boundaries of what a strategy game could do. It succeeded on three levels: as a character-driven story generator, as a game, and as an exploration of historical forces.
Ask most players what stood out about their CK2 experience and the answer would be the characters — and their hijinks. Even now, almost 10 years later, CK2 is virtually unique in making individuals the building block of its world. Those individuals, and their plots, schemes, dreams, and desires were the material for the rich stories that CK2 generated. I remember the sullen vassal who put aside his differences with my character to fight off a Seljuk invasion, and gave his life defending the realm; the aunt who invaded with a band of adventurers to press her claim; the Christian Norse I led to India; and the dynasty of Sinicised Persian exiles who finally — finally! — carved out a lasting home for their faith in Central Asia.
Underpinning these stories was that CK2 was a pretty good strategy game as well — skill, and a detailed understanding of the rules, paid off. My Persian exiles only survived against the odds because I learned how to pull every lever available: rushing east to seize lucrative trading hubs along the Silk Road; using the resulting income to keep mercenaries on permanent payroll; hiring Chinese strategists to train my outnumbered army; and learning the intricacies of the battle system — this was the campaign that taught me the importance of grouping cavalry retinues on the flanks. There is satisfaction in mastering the game’s systems.
Finally, CK2 brought to life one of the most important historical forces of the last millennium — the rise of centralised government. There is a quantum leap between a tribe, which falls apart every time the leader dies, and a feudal proto-state. There is a more gradual progression, over the course of the game, from feudalism to monarchical authority. Over time, levies, hereditary vassals, and a council jealous of its prerogatives give way to standing armies, viceroys appointed at the ruler’s pleasure, and absolute power. It’s a wonderful example of how gameplay mechanics can illustrate how and why something happened in the real world.
Ultimately, CK2 became my favourite Paradox game and one of the greatest games of the 2010s. With CK3 reviews promising, I look forward to this series giving me many more stories to tell.
