World Generation Parameters

Dwarf Fortress offers an unparalleled level of control over the worlds you generate, allowing you to craft the perfect setting for your next epic fortress. Understanding these parameters is key to avoiding common pitfalls and finding that ideal embark location. This section will guide you through the critical settings within the "Create New World" menu.

Accessing World Generation

From the main menu, navigate to "Start Playing", then select "Create New World". You'll be presented with a list of pre-defined world generation templates. While these are a good starting point, we'll focus on customizing them for a truly unique experience.

  1. Select a Template: Choose a template that roughly aligns with your desired world size and characteristics (e.g., "Medium Region", "Large Region"). Don't worry, we'll be changing most of its settings.
  2. "Customize World Gen Parameters": After selecting a template, an option will appear to "Customize World Gen Parameters". Select this to dive into the detailed settings.
  3. "Advanced Parameters": Within the customization screen, you'll see a button for "Advanced Parameters". This is where the real granular control lies.

Key World Generation Parameters

The Advanced Parameters screen is a dense but powerful interface. Here's a breakdown of the most impactful settings:

  • History Parameters: These settings dictate the richness and length of your world's history.
    • HISTORY_MAX_YEARS: This is arguably the most crucial setting. A higher value (e.g., 250-500 for a balanced world, or 1000+ for truly ancient realms) results in more developed civilizations, more historical events, and a greater chance of legendary artifacts and powerful entities. Lower values (e.g., 50-100) create younger, less established worlds, often with fewer ruins and less developed economies.
    • EVIL_DIFFICULTY: Controls the prevalence and strength of evil biomes and creatures. A higher value means more frequent encounters with undead, demons, and other unpleasantness. For a more peaceful start, consider a lower setting.
    • SAVAGERY_DIFFICULTY: Similar to evil, but for wild, untamed creatures and megabeasts. High savagery means more goblins, trolls, and potentially dragons roaming the wilderness.
    • CIV_NUMBER: Determines the number of starting civilizations. More civilizations mean more potential trade partners, but also more potential enemies.
  • Geographical Parameters: These influence the physical layout and features of your world.
    • REGION_SIZE: This defines the overall dimensions of your world map. Larger regions offer more embark options but can increase generation time and save file size. Common choices are "Medium" (65x65) or "Large" (129x129).
    • ELEVATION_VARIATION: Controls the ruggedness of the terrain. High variation leads to towering mountains, deep valleys, and dramatic cliffs, while low variation creates flatter, more rolling landscapes.
    • RAINFALL_VARIATION: Influences the distribution of biomes. High variation can lead to deserts next to lush forests, while low variation creates more uniform climate zones.
    • VOLCANISM_VARIATION: Determines the number and intensity of volcanoes. Essential for magma-powered industries, but can also lead to dangerous ashfalls.
    • MINERAL_SCARCITY: Directly impacts the availability of ores and gems. A higher scarcity makes mining a more challenging and rewarding endeavor.
  • Advanced Creature & Plant Parameters: These fine-tune the flora and fauna of your world.
    • MEGABEAST_CAP: Sets the maximum number of active megabeasts (dragons, hydras, titans) that can exist in the world. A higher cap means more legendary threats.
    • SEMIMEGABEAST_CAP: Similar to megabeasts, but for creatures like Rocs and Giant Spiders.
    • POPULATION_CAP: Influences the overall population density of sentient creatures.

Strategy for Optimal Generation

When adjusting these parameters, consider your playstyle and desired challenge:

  1. For Beginners:
    • Start with a "Medium Region".
    • Set HISTORY_MAX_YEARS to around 150-250 for a moderately developed world.
    • Keep EVIL_DIFFICULTY and SAVAGERY_DIFFICULTY low (e.g., 0-25) to reduce immediate threats.
    • Ensure MINERAL_SCARCITY is low (e.g., 0-25) for easier access to resources.
  2. For Experienced Players Seeking Challenge:
    • Consider a "Large Region" for more diverse embark options.
    • Crank HISTORY_MAX_YEARS up to 500-1000+ for ancient, lore-rich worlds.
    • Increase EVIL_DIFFICULTY and SAVAGERY_DIFFICULTY (e.g., 75-100) for frequent sieges and dangerous wildlife.
    • Raise MINERAL_SCARCITY (e.g., 75-100) to make mining a true test of endurance.
    • Increase MEGABEAST_CAP and SEMIMEGABEAST_CAP for more legendary encounters.
  3. The "Urist McGeologist" Special:
    • Maximize ELEVATION_VARIATION and VOLCANISM_VARIATION for a world rich in geological features, deep caverns, and magma.
    • Adjust MINERAL_SCARCITY to your preference – a high value makes finding specific veins a treasure hunt, while a low value ensures plenty of raw materials.

After adjusting your parameters, select "Generate World Now!". Be prepared for generation times to vary significantly based on your settings and hardware. Don't be afraid to experiment; you can always delete a generated world and try again!
