Who said it had to be a choice of five families. That is CK2. If Rome is the only focus there could be 150!
And then imagine the laws!!!!!!
Anybody who's read "Masters of Rome" by Colleen McCullough will know what I mean.
Laws to distribute public land among veterans, laws to change the composition of juries (knights, senators, classes, etc.), laws about how many days it should be for other laws to take affect, laws to change the voting system, laws to increase taxes from 1% to 2%, laws to temporarily take cash from temples for a promissory note, laws to...oh my gooooooood!
What I'd
like to see though, constructively speaking, is being able to choose a spouse for yourself and your family (you will play as
paterfamilias, naturally, in Rome). You set/accept a dowry, AI assesses the political ramifications, the lineage and honor of your gens, relations between the
paterfamiliaes, etc. I'd like that.
