The lead designer, Yoot Saito, who also worked on SimTower, produced this game as a sequel to SimTower, adding several new features while retaining the same general interface and style. The game's premise is largely unchanged from its predecessor; players must build a profitable and unique tower block complete with various amenities and living accommodations, whilst balancing the needs of the occupants.
