Open the Gameplay.constants file
This will allow you to change various diplomatic variables and relationship thresholds for treaties and missions for any of the 3 Sins versions.
The Gameplay.constants file you need to access for this is located in <Installation Folder>/GameInfo
So if you want to change the values for vanilla Sins, look for the file in gameinfo folder in the root Sins directory, such as:
C:\Program Files\Stardock Games\Sins of a Solar Empire - Trinity\GameInfo
If you want to change the values for gameplay in Entrenchment or Diplomacy, use the Gameplay.constants file in their respective folders, for example:
C:\Program Files\Stardock Games\Sins of a Solar Empire - Trinity\Entrenchment\GameInfo\Gameplay.constants
C:\Program Files\Stardock Games\Sins of a Solar Empire - Trinity\Diplomacy\GameInfo\Gameplay.constants
Locate the Diplomacy Constants
Now that you're inside the file you want, search for the string "playerDiplomacyAIDef"
