I personally don't like to think of plot structure as a fiction writer or a game designer, as I feel that tends towards a sort of Campbellian simplification that erases the rich complexities that occur naturally in stories. Also, so many of these plots exist around the idea of conquest, of triumphing over a foe, which is so often an unsatisfying arc, compared to the idea of living and breathing in a world. These plots also forefront a single protagonist, a chosen one, over the value of the group and the community, and I feel like RPGs in particular have an immense power in creating community-focused plots, which is something that rarely emerges from traditional narratives.
