i purposely left out any system with an implied ranking between the options, the correct format for comparing ranking systems is of course, as you say, a bracket
well that's what a good-aligned person would say anyway; i guess i see the D&D alignment system itself as taking a more neutral perspective about storytelling possibilities as opposed to being moralistic as such
part of what i'm going for in the chart is comparing how fans of the system relate to the system; people aren't using the D&D alignment system to, like, convince everyone to be more like paladins (that i know of)
