GameCritics offers an interview with the ever-awesome but relatively unknown Travis Stout, who worked on - among other things - Fallout: New Vegas and its DLC.
@ecavalli asked: Was there a firm directive to make the script more like the first two Fallouts than Fallout 3, or was that just a happy accident?
Travis: It was just a natural growth process based on the people who were there. It was a fun company to work for and many of them had worked on the older games, so it just happened that way. There was never any direct order from management, or anything like that. Also, at some points the humor was meant as an acknowledgement to fans who were familiar with the older titles.
@GreatCharleston asked: What did you enjoy writing the most in New Vegas?
Travis: EDI’s dialogue in Lonesome Road, or Muggy the mini Securitron in Old World Blues – Muggy’s voice actor totally nailed the dialogue and fit the writing perfectly.
