Extended Map Generation

Generate the landscape you want from the normal New Game settings, without opening the Map Editor. Extended Map Generation by Bobdike adds Extended and Extended Pro for Temperate, Desert, Subarctic and Tropical—all in one mod. CHOOSE YOUR MODE Extended covers the essentials: mountains, terrain height, rivers, lakes or ocean coverage, and forests. Subarctic also includes overall water amount, wet lowland regions and swamps. Extended Pro adds feature size and height, river forks and bends, lake detail and climate-specific controls such as cliffs, rolling hills, islands and volcanoes. Both modes use the same generation system. HOW TO USE Enable the mod for a new game. Under World > Generator, choose a climate's Extended or Extended Pro generator. Adjust Terrain settings and generate a preview. Descriptive sliders use Off, Low, Medium, High and Very High. Multipliers run from 0.25x to 5x in 0.25x steps. Direction, minimum river length and large basin mix have their own choices. Check displayed multipliers when reusing older settings. SUBARCTIC WATER Water amount sets the overall generation allowance. River, Lake and Swamp shares divide it between features; these are relative weights, not map-area percentages. If only lakes are enabled, they receive the full allowance even at a Low share. Lower Water amount to reduce the total. Wet lowland regions controls suitable terrain independently in both modes. Pro also offers lake size, depth and the mix of smaller lakes versus broad basins. RIVERS AND PLACEMENT Subarctic and Tropical's added rivers default to Off. River direction guides the main orientation while allowing bends and branches. Added rivers have irregular banks and clear trees from carved faces; Subarctic uses native rock shading on exposed banks. Settings apply to new maps. Town and industry density remain separate Civilization controls, although the resulting terrain can affect available placement sites. Actual shapes and counts vary with the seed and terrain; ship navigability is unverified. AI ARTWORK DISCLOSURE The cover image was generated with AI using OpenAI's image-generation tool.
