Here you can select the (Dis)Advantages that should count as unsuitable. If you select 'except for: (Dis)Advantage x' an exception is made if the character has (Dis)Advantage x. Then the (Dis)Advantage isn't unsuitable. This option is used for the Advantage Equipment Advantage. For some cultures Equipment Advantage is unsuitable, except the character is of Noble Birth. I don't know if it is useful in any other case.
