I get that it's for the mystery, but I'm so sick of series playing the pronoun game just so they can keep something mysterious. Like dawg, it's possible to make people talk normally.
I vastly prefer the ending of the first game, since you put more work into uncovering the mysteries of why you're here. In DR2, you put in far less effort for the actual mysteries, just answering a question every now and then in between the game expositing.
Despite being more bombastic than the first game's ending, I found that one to be a more satisfying combination of gameplay and story, especially since the game doesn't put on the kiddie gloves for you.
