When Crusader Kings 3: By God Alone comes out, I’m going to turn the Roman Catholic Church into a polyamorous love nest
Crusader Kings 3 will receive a new expansion titled ‘By God Alone,’ launching at the end of September 2026. The expansion introduces theocratic realm management to the grand strategy game for the first time, allowing players to take direct control of the Catholic Church and other religious institutions. This marks a significant gameplay expansion, as previously players could not fully control theocratic realms in the same way as secular kingdoms.
The expansion enables players to govern religious states within the game’s 11th-century setting, representing a new faction type in Paradox Interactive’s complex feudal simulation. The addition of theocratic governance mechanics expands the strategic depth available to players, who can now pursue religious-focused playstyles rather than being limited to secular rule. The feature addresses a notable gap in the game’s coverage of medieval political structures, where religious authorities held considerable temporal power alongside secular rulers.
Further details about specific mechanics, gameplay features, and additional content included in ‘By God Alone’ were not available in the source material, though the expansion is expected to provide substantial new content for the established player base of Crusader Kings 3.
