Random maps typically have a certain theme - for example a naval random map with many small islands, or a 'gold rush' map with a large amount of gold in the center of the map. The type of random map may also influence the game's artificial intelligence
Artificial intelligence (AI) is intelligence—perceiving, synthesizing, and inferring information—demonstrated by machines, as opposed to intelligence displayed by animals and humans. Example tasks in which this is done include speech re ...

Methods for generating such maps vary depending upon the topography
Topography is the study of the forms and features of land surfaces. The topography of an area may refer to the land forms and features themselves, or a description or depiction in maps.

In mathematics, a fractal is a geometric shape containing detailed structure at arbitrarily small scales, usually having a fractal dimension strictly exceeding the topological dimension. Many fractals appear similar at various scales, as illu ...
subdivision to create convincing terrain, whereas a game set inside a structure such as a dungeon may use two-dimensional maze algorithms. Some games allow the players to make their own random map scripts (RMS), a form of game modification
Video game modding (short for "modification") is the process of alteration by players or fans of one or more aspects of a video game, such as how it looks or behaves, and is a sub-discipline of general modding. Mods may range from small changes an ...
