Crusader Kings III is the ultimate grand strategy role-playing experience.

Shape Your Dynasty: Guide unique characters through history, choosing lifestyles best suited to their personalities and your ambitions.
Rewrite Medieval History: Dynasties will change and adapt to changes in family and politics, and religious beliefs are more firmly under your control.
Build a Mighty Kingdom: Use your vassals' fear of you as a weapon or call on familial obligations to persuade reluctant relatives to submit.
Experience High Drama: Stranger than fiction stories leap off the screen, as characters plot against you and events push you to extremes.
Learn as You Go: Guided advice to help newcomers navigate a rich medieval world. In-game suggestions tip you off to paths you might not have considered.
The Usual Crusader Kings Fun: Keep a stubborn council in line, scheme against your overbearing uncle or marry the rich duchy...oops, I mean pious duke or duchess of your dreams.
