PM Hamilton said:Example Number 1.
You are playing Tuscany and trying to form Italy. On the command decisions screen is a list of titles, one of them is entitled “Kingdom of Italy.” Next to the title is a list that looks similar to the National Ideas screen's square icons. They are all dark at the moment. The first on the row is called “Found the realm of Italy.” If you hover the mouse over the icon, it displays a short note, list the qualifications to use this icon, and the effects of the use of the icon.
The icons for Italy will only appear to those countries that can eventually found Italy - i.e. they meet the basic criteria. It will light up when you meet all of the criteria. When it lights up, you - THE PLAYER - can decide when to proclaim yourself Italy. Not random chance or external forces. Since this is a decision that rulers make, it is available to the rulers of the country in question.
It is a command decision! You’re in command! It’s your decision! You decide when to make it. You can wait until you feel you can defend your new title, or jump in and take the risk.
So basically you want the way kingdoms are claimed in Crusader Kings: Deus Vult be implemented to EU2.
