It's like Tiny Tower which was like SimTower but instead of building a skyscraper you're outfitting a mall. And nothing is more nostalgic (and/or fun) than re-living your mall hangout days, right? You can build your own now!
These building management-type apps have this crack addiction to them, OMG I need more sushi restaurants! Where am I going to put the stairs! All these questions of how to become a civil engineer or architect or building planner, they take over your mind. The better you build, the more fake people come, the better you feel about yourself.
