The quibble is not that we necessarily disagree with your premise. I guess I can only speak for myself, but my quibble is that this is not a unique quality of RPGs as a video game genre. Even the most basic of games ultimately have a story of some nature, whether that is contained within supplemental material (like an instruction manual, which was often where games, including many seminal RPGs, put their stories in order to save on memory/space for the game files) or even just largely inferred (many classic arcade games, thinking games like Missile Command or Pac-Man). I think that's, again speaking for myself, where I'm getting tripped up
