Maps can control the layout of objects and the like, but how the objects and surfaces look is actually controlled by the tilesets, how the resources look is controlled by the techtree, and the starting units are controlled by the faction. Maps have control over the placement or attributes of: * Land height * Water * Objects (such as trees or rocks) * Player starting locations * Resources (such as gold or stone) * Surface type (such as grass or road) * Camera height level (MGM only)
