Welcome to the building simulation game SimTower, which offers the chance to build and manage all the complex, interconnected operations of a modern skycraper. You build your empire from nothing and become the engineer and general manager of your structure. You can provide offices, coffee shops or apartments to anyone who is willing to pay.

Build a profitable and unique tower block complete with various amenities and living accommodations, whilst balancing the needs of the occupants. Lead designer, Yoot Saito, who also worked on SimTower, brings 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 similar to its predecessor.
