Before Bungie was bought by Microsoft they produced a little game called Myth and a sequel. The narrator was interesting because he was just a common soldier watching you and the other main characters. So his perspective was unique.
The other thing was that he had this weird tone to his voice. It was an English accent but he always had this weird element of being scared. Given that the narrator was a solider watching the world go to s***, it really created the setting well.
Haven't a clue what the actor's name was...
