Actually, I think the ghost needs to shut up and they need to add dialogue for the player's Guardian. Our player is the only Guardian in the known world that does not talk and the ghost does every bit of the talking. They could easily add the dialogue for either a male or a female character. There are several games where you can choose a voice, male/female and some even have the option of American or British accents. That was a big deal for me with all of the added cinematic and our character does not say one word.
