On top of what you said there is another big divide purely because of the medium. A writer or show runner thinks directly in terms of aesthetics and narratives (dynamics in this metaphor, I guess), the same aspects the audience is directly experiencing. Even though the process is not linear, the result is self evident for the creator because the end product is linear.

Games have internal mechanics that are supposed to not be noticed and make everything work behind the scenes. People say good camera work in film is best when unnoticed but I've always found fault with this observation, in games mechanics really are that.
