  - <!--Leoreth: define how often these optional civs should appear
  - value=0 Civilization never appears
  - value>0 Civilization roughly appears in every i-th game, where i is the entered value
  - (so to make this civilization appear every time, enter 1)
  - Note that if certain civilizations are controlled by the player, these civs will spawn regardless to provide a historical opponent -->
