While I agree to some extent it allows for immersion, perhaps in a game with a greater overarching story something like that could be achieved. However, we're supposed to be drawn into Isaac's struggle, his emotional connection with his ex-girlfriend or what-not, and it's literally impossible. There is no call and response. There's an invisible response, which prompts the next line from whatever NPC is currently interacting with Isaac, but I felt no urgency or betrayal at any point in the game because I was playing as a void. It allowed me to experience the blood and the shocks very well, in greater detail, but it left other parts of the game - namely the story and emotionality - bankrupt. The story would have worked so much better had Isaac actual lines of dialogue in the game.

The story for Uncharted isn't very good. It boils down to, reclaim artifact before it can be sold as weapon - but Nathan Drake is incredibly likable, which makes the story more entertaining, even though it is relatively vapid.
