It doesn't much matter to me if it's one single sentence or three. Video game dialogue is rarely well-written and almost never reflects my characters. I have a really hard time playing any of Bioware's games, for instance, because the dialogue Bioware's writers provide for my characters almost never fits my characters in any way. Too often I end up picking one of their lines of dialogue at random, and feeling like I want to put a hand over my eyes so I don't have to read it. I feel the same way about most of the dialogue Obsidian writes.
