I think you'd have to go to lines 4115-4140.
I.e
Spoiler :Code:if optionID == 0: #Cohesion return 1#"Medium" elif optionID == 1: #Mountains return 0#"Standard (Default)" elif optionID == 2: #Desert return 1#"Low" elif optionID == 3: #Tundra return 2#"Reduced" elif optionID == 4: #Plains return 2#"Very High" elif optionID == 5: #Jungle return 1#"Low" elif optionID == 6: #Forest Density return 2#"Increased" elif optionID == 7: #Wrap return 1#"East-West (x)" elif optionID == 8: #Player Starts return 0#"Full Flavor (Default)" elif optionID == 9: #Rivers & lakes return 2#"Increased" elif optionID == 10: #Advanced Terrain return 1#"On (place Ancient Forests)" elif optionID == 11: #Smart Climate return 1#"On (minimal effects)" elif optionID == 12: #Ancient Ruins return 1#"On (Place ancient city ruin clusters)"
And the legend for the return valuesis given in lines 3975-4092.
