heres a few ideas
1. after you beat one city and move to another you should be able to keep track of both at the same time not abandon the old one
2. to me a suburb should be at least 10-35 houses for familys not 2 and you should be able to house in other areas such as hospitals (i mean come on the hospitals are 3-10 story's high full of rooms and u usually only have 2-3 people injured and then the rest are empty rooms.)
3.you should be able to keep track of familys as well since they are mention (they could server the purposes of farming, supplying, and making food.)
