What players say

84% of 109,373 reviews are positive · 70% of 739 in the last 30 days

Players praise the emergent political and family stories, character-focused dynasty play, and mod scene. The dominant complaint is the volume and price of DLC, with players saying too much content and some important mechanics are locked behind expansions. Some also report frequent multiplayer desynchronization and worsening memory use on lower- and mid-range systems.
