I would disagree with the choice of words here, yes their stories are often not super deep or intricate, but I do believe they are extremely interesting, specifically because they are presented in such an appealing way.
Just the elevator pitch for Hades sounds amazingly interesting, “you are the son of Hades fighting his way through procedurally generated dungeons to escape hell”, fuck yeah! Tell me more!
And the impact is definitely there as well, because while depth is missing, the qualities you described make what little story there is quite impactful.
Of course this is all just my opinion, but you can’t tell me that “you participate in ritualistic basketball games to free your comrades from a prison wasteland” doesn’t sound interesting.
