I wanted to make as many grand mansions as i could. I started the plebs and equites houses in the north of the map, and after i had the denari i did the villas in the south, then made a few more plebs and equites near the villas. You can't get a higher population on this map than the one i did, food is a real pain. Was one of the most beautiful cities i made so far. (23000 dennari)
