Moon Tycoon

Moon Tycoon is a city-building computer game released in 2001 by Anarchy Enterprises and Unique Entertainment. It is based on the creation of a lunar colony or city. Anarchy Enterprises described it as the "first 3-D Sim game ever", and noted that it has similarities to SimCity (which at the time was 2-dimensional).
