That is why I referred to fantasy tropes.
I don't think introducing modern, rationalist theories of advancement - scientific advancement, industrial advancement, sporting improvement, etc - into the game really strengthens its fantasy feel. That would be a better fit in Blade Runner or some other modernist/sci-fi setting.
Whether, or in what sense, literary criticism is objective or subjective seems a bit off-topic. But it's a thing that people do. They criticise and analyse literary works, films, plays (both scripts and particular productions), etc. I don't see why criticism of D&D or roleplaying fiction more generally is out-of-bounds.
