There was a thread in the colosseum about modifying the civil war. I think the gist was that if you start a civil war, there was some chance that some of your family members would remain loyal to the senate, and some chance that other families might lose members to you. This would reintroduce loyalty (a great M:TW trait).

It would be nice if the senate offices given out to family members allowed you to stick it to the other families (and vice versa). I think only one office really affects the game now. But imagine, Biggus Dikkus Julii is given the office of Gladitorial Inspector, "Sorry, Nottius Maximus Scipii, your colosseum in Syracuse does not meet code, you will have to shut it down for a year". Nothing too major, but you could affect the relationship with the other families and annoy them greatly.
