@RoyalJohnny242 @Vsolid I know exactly how this is going to sound, but it’s just an observable phenomenon. The more you see cousin-marriage in a people, the harder they are to rule. What any of this has to do with playing cards is that this is not a phenomenon accessible or desired by most people but you can at least simulate some of its effects by learning what your blood relatives played before technological amusements and finding those people who still have a foot in the old ways. You will have a chance at accessing those cultural blood memories.
