In CK2 game rules turn off "Titles Named After Dynasties" and "Cultural Title Names"
I converter CK2 1337 game start to show improvments: Ottomans, Granada, Tlemcen, Egypt, Tripoli, Karaman got nicer names and flags but its not only about names
With "cultures title names on" ottomans have general ideas and generic unit models but if you turn it off they got unique missions and unit models from EU4
And start with Ottoman Government reform
Same goes for other tags like Granada
Or tags in India like Orissa
and many others who have unique missions and units but EU4 converter convert them wrong if turn culture tags on in CK2
For some tags its just fix name and flag which is still nice
Unfortunately it does not fix ideas problem and all these tags still will get generic random ideas instead of existing unique ideas from EU4
