Crusader Kings II

The base game is free, but a large catalogue of paid expansions unlocks mechanics and systems that change how the game plays.

Play turns on murdered kin, assassination plots, imprisonment, plague and executions, with named characters dying as a normal part of the story.

The player orders murder plots, imprisons and executes rivals, and seizes titles by conquest as core mechanics.

A secret Satanic society lets characters summon demons and carry out blood rituals within the world.

Affairs, seductions, concubinage and out-of-wedlock births are handled through text events and dialogue, with nothing sexual shown.

Warfare, assassination and executions are core actions but resolve through map tokens, army counts and character portraits; no blood or wounds are shown.

Drinking features in feast events and characters can carry a 'drunkard' trait; alcohol is described rather than a player action.

Hunting events let the player pursue and kill game such as boar as an ordinary lifestyle activity.

Captured prisoners can be maimed — blinded or castrated — through menu decisions; harsh treatment is described in text rather than shown.

Characters with the 'depressed' trait can die by suicide in text events.

Maiming prisoners, such as blinding or castration, is available as a text decision and is described rather than depicted.

Expansions are optional one-off purchases with no timers, energy gates or escalating spend-tier offers.
