A typical world has cities, towns, rivers, forests, bridges and other landmarks. Cities and towns generally have all the common establishments generally found in real world such as houses, departmental stores, malls, parking lots, swimming pools, hospitals, malls, etc. Exotic locations such as Science Labs, Military installations, missile silos can be found in remote places throughout the whole world.
