SimCity

SimCity is the first of a of entertainment/education software, called SYSTEM SIMULATIONS. It provides you with a set of rules and tools that describe, create and control a system. In the case of SimCity the system is a city.
The challenge of playing a SYSTEM SIMULATION game is to figure out how the system works and how to take control of it. As master of the system you are free to use the tools to create and control an unlimited number of systems (in this case cities) within the framework and limits provided by the rules.
