And maybe some terracotta rooved houses and buildings with the dark facades?
Houses with terracotta roofs are typical italian...everywhere you go (apart from the mountains maybe) you'll find those kind of roofs...talking for experience as I'm italian ::) think there's something similar (not identical though) already available...Actually now you've made me think about it there are not many italian historical buildings available for SC4...Like buildings from Rome...but also Milan's cathedral,ecc...
