Crusader Kings III continues to grow six years after its release. Monthly data compiled by players from SteamCharts shows that the average concurrent player count during the game's sixth "game year" was approximately 19,300, higher than the roughly 15,500 recorded in its first year.
This statistics report uses the game's September 2020 launch as its starting point, defining each period from September of one year to August of the next as a "game year." The average concurrent player count for Crusader Kings III during its second year dropped to approximately 13,500, but has since risen annually, reaching about 19,300 between September 2025 and August 2026. The above data only covers the Steam platform.
Including the impact of the September 30 release of the Crusader Kings III: Legacy of Persia expansion, the average concurrent player count over the most recent 30 days was approximately 19,800. In November 2025, Crusader Kings III: Paths to the East expanded the game's content to East Asia, achieving an average monthly concurrent player count of around 29,000, marking its best monthly performance since launch.
The article suggests that the addition of Byzantine administration mechanics and landless adventurer gameplay in Crusader Kings III: Roads to Power (2024) may have been a turning point for the resurgence in concurrent players. Discount events and continuous content updates may also have contributed to long-term engagement. However, these causal relationships are not official conclusions.
