Export the save to EU! Yeah it's a terrible blob, that's why you play someone in the new world and try to defeat it!
You saying that is like asking me to cut off my face, haha.
I hated this achievement because it's super goddamn boring.
The only time I really had fun during the entire thing was in the beginning, which I wrote about
here and
here.
After I created Francia the game became a complete chore to play, with the constant micromanagement of viceroyalties, plots, and imprisonments.
The only other noteworthy events were:
1. When I conquered the Byzantine Empire, created the Roman Empire, then liberated the Byzantine Empire so I could be the French Roman Empire.
2. When I discovered those immortal superwarriors and recruited them into my army.
3. When the King of Jerusalem (my dynasty member) created an antipope and I went over there, smacked his face in, and conquered the entire thing. Then I reduced his holdings to just a single barony and had him excommunicated. Since he was excommunicated, I could imprison him with no penalties so I kept imprisoning, torture, imprison, humiliate, imprison, mutilate, etc. until he reached something like -1000 relations with me. Yes, I was that bored.

So if you ask me to import this I will say "no goddamn way". It's way too boring.
