Sorry to throw things in your forum, but I wonder, what would they decide on various matters and how would they react? First off the territory of Italy. That would be a good event. How much would they want to get back or conquer? Second is the form of government. Will they be attempting create the Roman Republic or Roman Empire? (If they manage to survive the war, than probably not one country would care of their form of government.)
Equipment and organization of their armies, political asylum, prisoners of war etc.
Relation to a possible southern nation, or occupied land.
What to do with the Black Shirts?
Industrial independence? (I mean they need to cook with what they have, so they would probably focus more on mining.)
New RSI Navy.
Relation to Switzerland (maybe asking for a loan.)
RSI propaganda and media industry (along with movies.)
Terrence Hill, because why not?
How to react to the Cossack units and ragtag villages in Carnia?
