Todd Howard har anerkendt, at Fallout 4's dialog ikke var lige så stærk som i andre spil fra studiet. Dette har han afsløret via et nyt interview med GameSpot under E3, og her sagde han:
"The way we did some dialogue stuff [in Fallout 4], that didn't work as well. But I know the reasons we tried that - to make a nice interactive conversation - but [it was] less successful than some other things in the game."
Hovedkritikken bag Fallout 4's dialogsystem er manglen på forskellige muligheder, og det skyldes hovedsageligt at hovedpersonen denne gang har en stemmeskuespiller tilknyttet
Dette forsøgte Todd Howard og hans hold at løse i Far Harbor-udvidelsen:
"The choices you have in the end. When we have an opportunity with something like Far Harbour, like 'Okay, how many ways can it end?' Let's give them more choice with something like that. I think it's an ongoing thing, and I think that kind of feedback we get is really, really helpful. And you're right that everybody does have an opinion, and I think that's good."
