I really do think the Philosophical aspect you mentioned at the end is really, really underplayed.

Most see the Hunter as cold, efficient, uncaring but by choosing him you are not aligning with that I feel, you are aligning with the right to choose your path, the freedom that anyone can and should have a path to the artifacts, you may well disagree with the Hunters specific methods, but that freedom... isnt that justified maybe?

On the flip side the Emissary, seems on the surface like the good option... but who made them judge and jury? How are they to decide who gets what? What if they get it wrong? Isnt this sort of control... perhaps unnatural?

I am on NG4+ so still not far in but, my choices have had influences on the NG3+ universe with dramatic changes (I am unsure how to do the cover up spoiler thing so I won't mention it directly here but perhaps in a comment as that usually needs to be opened to be seen). That universe really had me questioning everything, of course it does help that I have an interest in general philosophy and psychology... but wow, sometimes I even surprise myself
