I plugged Dystopian Port City into google and came up with this gem:
Dystopia -- A fictional world created for homeland defense and security educational exercises..."Dystopia itself is a standalone product. It is a collection of geospecific and meta data that creates a robust, deep virtual environment in which exercises, games and scenarios can be created. This collection of data includes spatial information, 2D map products, and a database of metadata about the people and places located in this world. Dystopia, by itself, is not a game or exercise - instead, it provides a context for those types of learning activities. It must be embedded into an application or interface that contains game logic or exercise rules. It also can be used for tabletop or other live exercises that do not use software, but impose rules explicitly and use the electronic viewing and searching products of Dystopia for efficiency."
