As much as I tried to like this game and see a Sim Tower successor in it, it's not. Yes, it has a greater variety in offices/appartments/stores and so on, but it lacks the most (if not only) challenging feature from Sim Tower: Elevator-Management. Like stated in other reviews, the UI and Gameplay are full of flaws, and once you unlocked a few of the "higher" rooms, the game gets really boring - if not earlier... I'd wait for a 75%/80%/90% discount...
