So far in my Roman campaign I had enough family members to have one in each city plus the generals who fought battles on the front. Now I've reached a number of provinces where I cannot do that any more. I have tried resolving this issue by training allied generals. This means that most of the newly conquered cities have a type IV government.
What is the conventional way of handling a large number of provinces? Do I make Type II governments and pack them full of garrisons if I don't have any available family members or use Type IV/allied generals on everything I conquer? Should I leave Italy empty of family members and send them to govern abroad?
