@Demotruk: What does 'value' have to do with authority? The market can reject a game, yes, but that has nothing to do with Nintendo's authority over its contents. Nintendo can chose to pander to the masses, but they do not have to, nor should they, necessarily. It is a red herring to pretend that authorial intent is (or should be) a product of corporate interests, or vice versa.
As to your second point, I'm a bit lost, actually. My point was that the early Metroid games had some amount of characterization, and that it was meaningful.
This rebutal of yours... Yes? That's one way of approaching the issue (though I think your example is rather poor - Frodo is purposly distanced from the reader at the end of the story). A valid one, but by no means the only one; Lolita being a particularly famous example of a work with a distinctly un-relatable protagonist.
