Cain appreciated the performances and storytelling, but singled out how the show nailed the Fallout “vibe” as its biggest achievement. “I was just looking at all the props,” he said of one scene. “I realized after a few minutes went by that I had not followed the dialogue at all, because I was so engrossed by it visually.”
On a more sour note, Cain took time to address the way fans of the series can behave poorly online, particularly regarding any perceived rivalry between Fallout entries developed by Bethesda (3, 4, and 76), and those from Interplay, Black Isle, and Obsidian (1, 2, and New Vegas). Cain spoke positively of Todd Howard, and said that “Some of the stuff you [series fans] say online is so off.” See also: the debate about whether the show somehow overrode or ignored the events of those non-Bethesda games, which has since been denied by a senior developer at the studio.
It is not the same engine but a ever evolved one. Saying that it is the same engine would be like saying that UE5 is the same engine as UE1
UE has evolved and changed over time to use new hardware features and adapt to new player needs.
Gamebryo is still the exact same engine that ran Morrowind, just running worse games on faster hardware with more memory. It even still has some of the same bugs, which community patch mods have had to fix for every single game (except Starfield, because that’s become such a clusterfuck of bugs and poor design that even the most dedicated modders have given up).
