+`diffMode` : Controls what mode contract/system difficulty operates on. Options:
+
+    - NotActive: The default mode, Global difficulty patches are not applied at all
+    - System: Difficulty is based on systemdef defined. This is functionaly the same as NotActive, but Global difficulty patches are applied
+    - Company: Difficulty is based on the value of your best fieldable units. Note: When this mode is active, the Difficulty Filter in the starmap will not work (biome filter still works)
+    - Reputation: Difficulty is based on your standing with factions.
