The FarmVille aspect is annoying and doesnt make sense as others report.
The primordial silo communities (Chinatown, etc) take FOREVER to build because to upgrade them takes A) a lot of domestic items like cheesecakes, smoothies etc. And B) imported items in exchange for A LOT of manufacturing.
This really slows down progress and its not a lot of fun anymore. I could keep scanning the market for the imported specialty items required to upgrade those neighbourhoods but Id have to be scanning way too of ton which would be too monotonous a solution.
