SimTower

SimTower allows the player to build and manage the operations of a modern, multi-use skyscraper. They must plan where to place facilities in the tower that include restaurants, condominiums, offices, hotel rooms, retail stores and elevators. To prevent tenants from vacating their properties, the player must keep their stress low by fulfilling their demands for medical centers, parking lots, recycling facilities, clean hotel rooms staffed with housekeepers, and an efficient transportation system, which involves managing elevator traffic. SimTower, which was built around an elevator simulation program, places a strong emphasis on good elevator management.

The game begins with a one-star tower with limited building options. To increase the tower's star rating, it must attract more tenants by providing more living space (or office space, and later in the game, hotel and various types of commercial space). New facilities are made available while the tower progresses from a one-star rating to a five-star rating. The highest achievable rating is the designation of "Tower" which can only be awarded by building a cathedral at the very top of a five-star building with all possible tower levels above ground developed.

Developed by Yoot Saito of OPeNBooK, SimTower was originally titled The Tower. It works on computers running the Microsoft Windows or Macintosh System 7 operating systems; the game will operate on 68k-based Macs at a minimum. It requires 8-bit colors and four megabytes of random-access memory. Graphics and sounds used in SimTower are similar to those of previous Sim games, and high-resolution graphics are also used. The sound effects are kept to a minimum; noises that are played in the background include office "buzz" and elevator bells.

While attending Waseda University, Saito played SimCity on the Macintosh, which prompted him to pursue video game creation after graduating. His first game was a simulation title that was part of a future media project for a publishing house. When Saito asked to develop a second, the business refused because it was not a video game company. He left the company to personally produce the second game, which built on ideas he conceived while working on his first: elevators and towers.
