I remember doing CK2 games as an Irish count forgot which one, and as a converted Imperator save as Britannia. I also remember somewhat long-running CK2 games starting as Francia and as the Rurikids in 867, but I don't think I played those through all the way to completion. I haven't played a full CK3 game yet.
Tags that will let me get achievements on the way and that will let me imagine nice historical narratives are a plus.
Update 2025-11-17 (PST) (AI summary of creator comment): The creator is currently playing as a custom noble family (the Bǐ (比) Family) in the All Under Heaven DLC.
1,000@Tetraspace At the 867 start date, the son of the ruler of Þrándheimr in CK3 is Hrolfr, who in CK2 is identified with Rollo, the first duke of Normandy (though in CK3 they're different characters). So with some leaps of logic, this is tracing back one ancestor branch of the English monarchy all the way.
