Goals?
One: Blob.
Two: Screw over Castile/Spain (such an ugly color and so much of it).
Three: Screw over Austria (such an ugly color and so much of it). Four: Screw over anyone who reaches Ewiger Landfriede (I refuse to allow the HRE to form, and if they manage to revoke the privilegia, the number one priority is to prevent them from making the abomination that is HRE gray a reality, but no internal wars is kind of the tipping point).
Five: If anyone else is ruled by the Habsburgs, put them out of their misery (okay, so at this point, I'm just bitter at house von Habsburg (almost as bad as the bizarre mishmash of Karlings in CK2)).
Six: Avoid other unsightly things. I'll sink the DIP to integrate Lithuania because the Commonwealth is ugly and never form Scandinavia simply because the Kalmar Union flag is an abomination.
Seven: If it still exists, end Byzantium (revenge for CK2 and because, honestly, after all the romanophilia, I've come to despise the whole Roman thing).
Eight: Encourage alternate nation formations (eg. Novgorodian Russia, Lithuanian-Polish Commonwealth)
