Art can serve several purposes. Your tastes are valid as a preference, but fun and escapism are only a small part of what games as an art form can provide. Would you critique a piece of visual art (for example, Guernica) by saying “this isn’t very fun”?
Split personality character, listed as “Dog/God” in the wiki. Dog is the half that is subservient and dumb, God is the half that is cold and calculating. The character’s questline has you helping one or the other take over fully, or helping reconcile them into a single personality. Pretty interesting one!
I agree with the point, but would argue that choosing not to link the fire is distinct from never adventuring at all. Letting the dark gradually take over with no wielder/ruler would make events like Oolacile much more likely than if a Lord of Dark was there to control and direct that power, imo.
