Crusader Kings III is already one of the best dynastic grand strategy games. With Steam Workshop mods, it becomes literally infinite. Here’s our selection of best CK3 mods in 2026, sorted by type.

Top total conversions
1. A Game of Thrones (AGOT)
The most ambitious total conversion on CK3. Transposes Westeros + Essos with original houses (Stark, Lannister, Targaryen, Greyjoy, Martell, etc.), playable dragons, magic, seasonal cycles. Regular updates. Hundreds of hours of exclusive content.
2. Elder Kings 2
Elder Scrolls (Skyrim, Morrowind, Cyrodiil) total conversion. Play Dunmer, Nord, Bretons, Khajiit, Argonians, magic, daedra, and all TES lore. Ideal alternative for Bethesda fans.
3. Realms in Exile
Tolkien (Middle-earth) total conversion. Gondor, Mordor, Rohan, Arnor, Harad. Covers 3 different ages.
4. When the World Stopped Making Sense (WtWSMS)
Dark Ages conversion: fragmented Europe from the 4th to the 10th century. More historical depth than vanilla, with barbarian invasions, folk migrations.
Top overhauls
5. CFP: Community Flavor Pack
More portraits, more clothing, more visual diversity. Massively enriches visual immersion without changing gameplay.
6. More Interactive Vassals
Makes vassals much more alive: they ask favors, act politically, have personality. Major overhaul of your subjects’ AI.
7. Sinews of War
Economic and military overhaul. Adds troop fatigue, logistics, mining deposits, a more detailed economy.
Top QoL and bookmarks
8. More Bookmarks+
Essential. Adds dozens of extra starting bookmarks (Viking invasions, Crusades, Mongol Empire, feudal Japan, etc.) to diversify runs.
9. Ethnicities and Portraits Expanded
Over 400 new portraits to better represent historical ethnic diversity. Subtle but very effective.
10. Better UI
UI improvements: enriched tooltips, keyboard shortcuts, more info visible at a glance.
Conclusion
The best CK3 mods depend on what you want:
- Total change of scenery → AGOT (Game of Thrones) or Elder Kings 2
- Historical realism → CFP + WtWSMS + Sinews of War
- Vanilla refresh → More Bookmarks+ + More Interactive Vassals
