Y'all

I started a new campaign with the Scipii faction the other day. I captured the rest of Sicily, and then did nothing else. Built a couple of full stack armies here and there, just waiting until one of the other Roman factions decided to take Rome. I managed to get to 178 BC, and still nobody was budging!

Do you guys think that the game is programmed in such a way that you are the only Roman family who will try to attack the Senate? If it is, then that sucks big time.
Has it ever happened to any of you guys that another Roman faction has attacked Rome?
