This system is a town automatic generative system for a game maker. When a user sets a value to each level, the town which a user desires is generated. The form and texture of a town change with the values set as each level. For example, the type of the town used as the first foundation of a level has divided into five kinds. The width of a town, the interval of a building, etc. are determined by which kind is chosen. Moreover, this system does not generate a realistic town but it aims at making the town appropriate for a game.
