- Dynamic country tags are created for CK2 realms without equivalents in the base EU4 game. Flags are carried over for the nations as well for CK2 nations that have no equivalent in EU4.
- Nations that have an equivalent in EU4 gain their national ideas. Nations without equivalents gain randomly generated ideas (though at the moment there appears to be a glitch where generic national ideas appear on the launch screen, as it seems ideas are only generated upon first launch of a game using the generated mod. It is recommended to pick a nation, start a game, and immediately save and restart back to the screen that lets you select a nation in order to have the actual generated ideas appear).
- Unique national ideas for Aztec, Hashashin, Inca, Israel, Jomsvikings, Karlings, Knights Templar, and the Roman Empire.
- With Sunset Invasion active, The Inca and Aztec empires will have the High American tech group, as well as large empires in the New World.
- Provinces convert to a dynamic amount of development, depending on total income generated by holdings in corresponding provinces in CK2 (as of CK2 2.7.2). Economic view in CK2 gives an preview of the probable development in the export.
- Reformed Pagans all have their own unique religions in EU4. Reformed Norse can also choose their own personal deities.
- Most Unreformed Pagans become Animists, however CK2's Tengri nations will continue to be Tengri in EU4.
- Zoroastrian nations continue as their EU4 equivalent; unreformed Zunists become Zoroastrians.
- Reformed Zunists remain Zunist.
- Hellenics also have their own unique religion.
- With the Sons of Abraham DLC all heresies will also become unique religions. Without the DLC though heresies will be only be converted if they have overtaken their parent religion in the game.
- With Minimal Crown Authority (Autonomous Vassals), kingdom-level vassals and duke-level vassals will become vassal states rather than integrated into the whole realm.
- With Conclave enabled, this is tied to a realm's council power. With council power abolished, the whole nation will stay independent. If any council laws are active, there will be some vassals. The centralization law doesn't affect this.
- A maximum of 4 EU vassals are created from a nation's largest vassals. The rest will stay part of the nation.
- The Holy Roman Empire is implemented using EU4's HRE mechanics. All vassals remain unless crown authority is Absolute.
- The seven largest vassals within the empire will become electors and the rest of the direct vassals will become normal princes.
- If crown authority is absolute the HRE becomes a single nation instead. With Conclave DLC, the HRE becomes a single nation when the council is not empowered.
- CK2 To EU3 Converter - an older fan-made mod for transferring CK2 to Europa Universalis III.
