Hmm lets see,
-some houses look too shiny thats worth fixing,
- the landing craft should be Spreaded a little bit more to make the battle for Lungomare and Other first flags more intense,
- making the flag Hidden Supplies more dangerous, its not worth defending,
- making the castle more vulnerable to attacks, maybe with a tunnel, a destructible wall etc... Another sneaky way to get into the castle,
Yeah, these are the "magic touches" wich could be applied IMO
