The Blue player has an Income of 4 and Civilization Upkeep Cost of 5 . As the sum of these is 4–5 = –1, they must Pay one Money for their civilization to remain solvent. If their Money Storage Marker is at 0, they must either Trade other Resources for Money or Abandon Sectors until their Civilization Upkeep Cost is less than or equal to their Income. Abandoning one Sector without a Population Cube on a Money Population Square would change their Civilization Upkeep Cost to 3 , allowing them to Pay their full Civilization Upkeep Cost and gain one Money.
After Paying their Civilization Upkeep Cost, Blue would then collect 6 Materials and 3 Science as their Materials and Science Production.
