I have had to restart my campaign several times now just out of frustration with the settlement management system. I like to play as Scipii, and I usually take Sciccily without too many hiccups. but as the game progresses tiny little empire just crumbles in on itself due to recession and being un able to provide adequate troops and troops types to defeat the carthaginians.

I always massacre each settlement I take over to reduce the cultural difference and curb the squalor down etc. I try to build nearly every turn, I build sewers, baths etc etc however it's only a matter of time untill the squalor sky rockets and most of my cities fall into the recession and I am unable to progress my military efficiently. For me the settlement manage is just ruining the game for me. I find it very frustrating and is ultimately putting me off playing the game completely. What am I doing wrong?
