General Balance[]

  • Separated some early yields from the capital. Click for details.
    • 2Science.png, 2Gold.PNG, 2Culture.png, 2Production.png Palace (was 5, 5, 5, 5).
    • Food.png, 3Production.png, 1Gold.PNG per city (was 2, 1, 0)
  • Happiness
    4Angry.png per city (was 3).
    4Angry.png per Puppet.png city (unchanged).
    5Angry.png per Occupied.png city (unchanged).
    4Angry.png per 4Citizen.png in non-occupied cities (unchanged).
    4Angry.png per 3Citizen.png in Occupied.png cities (unchanged).
  • Golden Ages
    • Cities produce +20% to all yields during Golden Ages. Click for details.
    • 400GoldenAge.png base cost for a Golden age, and +300GoldenAge.png more for each additional GA (was 500, 250).
    • Happiness continues to contribute to the golden age counter during golden ages (disabled currently)
  • Increased all non-specialist Science.pngCulture.pngFaith.png income and expenses to 200%. Changing both income and expenses has minimal direct effect on gameplay, but alters the percieved value between these and other yields, which has a positive impact on other balance efforts.
  • 30Food.png base cost to grow cities (was 15).
  • City border expansion via culture is slightly slower than vanilla. Via gold it is cheaper at first and more expensive later. Both Gold.PNG and Culture.png can expand to the 4th ring around cities (was only culture). Click for details.(disabled gold ring change currently)
  • Doubled the gold return when an opponent beats us to a World Wonder.
  • Most early buildings no longer have a purchase cost penalty. Purchase efficiency now depends mainly on the cost of each individual building (more expensive buildings are more efficient to buy).
  • All buildings cost increased roughly 2x. Wonders and Projects increased in cost roughly 1.4x
  • Domestic Trade.png trade routes favor large, populated cities more, and tiny cities less. Less gold earned from trade routes than vanilla.
  • Settlers cost more to purchase.
  • Minimum city distance is 2.
  • The capital’s radius is visible at the start of the game. Click for details.
  • Improved A.I. city placement.
