I'm not sure how to feel about adapting video game stories into other mediums in general honestly.
I think a large part of what makes a particular game's story as good they are is the interactivity that inherently exists in games. Say what you will about Sony's "movie games," but they are objectively more interactive than any movie. This, in turn, allows audiences to have a much easier time empathizing with the protagonist in a game when compared to a movie, assuming the quality of writing is equal between the two.
Arguably all game's stories are written with that interactivity in mind, and taking that away only weakens it in my mind.
I mean hell, I can't think of a single adaptation of a video game into another medium that was good, the best they ever seem to do is mediocre and that's seen as some huge victory.
(No, the Witcher does not count, that was derived from the books, not the games.)
I just don't think I'd care as much watching Joel exterminate the fireflies to save Ellie as I would actually doing it myself, or appreciate Kratos retrieving his Blades of Chaos without feeling the disappointment of their absence as I play.
Maybe they'll surprise me, I'm certainly not hoping Sony will fail in their endeavors, but based on history it doesn't seem like a prudent way to be spending their money, especially when the competition is getting stiffer and more aggressive in offering consumers compelling games and services.
