- Shattered and Random Worlds: Start your game on a fictional map of Europe as a small realm fighting for space, or on a random map with historical analogues for the great kingdoms of yore.
- Warrior Lodges: Join a Pagan warrior lodge and raid your way up the ranks, unlocking access to powerful allies and greater military skill.
- Legendary bloodlines: Descendants of great warrior heroes will have bonuses that match the accomplishments of their forefathers, including historical bloodlines of Charlemagne, Genghis Khan and others..
- Sway or Antagonize your neighbors: Try to win a reluctant vassal through charm and persuasion, or provoke someone you want to push into conflict.
- Sainthood: Pious Christians can become canonized, passing on their glory to their descendants and making their resting place a site of great value.
- Coronations: Feudal catholic/fraticelli kings and emperors must find clergy to crown them, since all power descends from the heavens.
- New Crusade events: Deeper gameplay for the religious wars of the era.
- New Succession laws: A Pagan Elder Council may have the final word in how a realm is divided among heirs, or a ruler may challenge his brother to combat to unify a realm.
- Playable Hellenism: A ruler can revive the dead ancient Greco-Roman religion when meeting some strict requirements.
- New portraits for the French, Arabic, West Slavic and Italian cultures.
- And much more: Changes to religion, custom names for people or objects, deeper baptismal mechanics, lists of people you’ve killed, and other small changes for flavor and variety.
- Map and setup improvements (including Tartaria, Russia, Scandinavia, the Wendish Empire, the HRE, Italy, Francia, Britannia, Hispania, the Byzantine Empire minus Bulgaria, Wallachia, Mali, Abyssinia, and North Africa).
- New game rule, reducing "border gore" if enabled.
- Reworked Crusade mechanics for Catholics and Fraticelli.
- Reworked character view interface.
- Added flavor events around lifestyle and battles
- Reworked elective succession laws. New princely elective for the Holy Roman Empire and imperial elective for the Byzantine Empire
- New imperial government for the Byzantine and Roman empires
- Rebalancing of the personal combat rating system
- to be added.
- Holy Fury patch was initially targeted as "patch 2.9", as visible in some documentation in game files.
- The project lead had to sell a 1 full year development cycle to the product manager, probably the biggest development time for any Paradox expansion so far.
