- Italy will now leave the Empire around 1500 if the entirety of the 'Northern Italy' region isn't brought into the HRE by then. Player nations have the option to choose to remain.
Ok, now I really don't get what you're trying to do with Italy. What does it mean "brought into the HRE"? Aren't most northern italian nations into the empire to begin with? Or it means they have to be conquered by Austria, the emperor, to remain in the empire?
And really, what's the point of keeping the italian states under the HRE and then pulling them all out when some arbitrary date comes up? In the real world, Austria didn't just wake up on the 1st of January 1500 and said:"You know what? Screw the italians! They're not part of my club anymore!" If you want to simulate the german emperors's disinterest of the intrigues and wars of italian princedoms and republics, then don't put them into the empire at the start of the game. It's that simple.
