>I don't think anything adds more dialog
There's "Roleplayer's Expanded Dialogue", "Start Me Up Redux", new ending mods like Subversion and Danse's Dilemma, and some quest mods that didn't bother to reuse the vanilla lines.
None of them will really improve the story but at least they can remove the "PRESS X TO SHAWN" from your character's backstory.
