The details can often round out the overall impression, atmosphere and immersion.
I'd like to see something like this in the beginning to make good use of the voiced protagonist, strengthen the disillusionment and create a connection to the Fallout lore without shoving it down your throat:
Codsworth: "Not eating properly for 200 years will do that I'm afraid, hahaha."
PC: "200 years? This is a wasteland. Everything's in ruin. Is... is there anyone still alive?"
Codsworth: "I haven't seen any decent people for quite a while. (Sigh) The olden days are surely gone, Master Howard."
PC: "I can't believe it. No sign of any Garden Of Eden out here. Vault-Tec... it was all lies."
Codsworth: "Well, I'm delighted that I could stay close to my Master's resort. This is a safe location and I'd advise that you rest here for a while and get your bearings. You look famished. Perhaps I can whip you up a snack?"
PC: "What? Food?... Yeah, sure, I... I need a minute to think.
