that would work. tho the companion systume would have to be redone from scratch. with the way it is now. an making it to that way from it is now would cause alot more error's. as far as i could tell. tho they games creator know's what there doing. This opinion is just what i am seeing withe the error's my self.
They can use the same system as the equipment system were you have alot of stuff but only the ones you selected have an effect in battle and name tham first companion and second companion
And maybe even make them affect your status when they are selected for example character A gave you +1charisma , character B gave you +2 strength and so on
Great game by the way
