“No, I haven’t sat down to play the games,” said Walton Goggins, who plays pre-war movie star Cooper Howard and his post-war counterpart The Ghoul. “And I won’t. I won’t. I won’t play the games. I’m not interested.”
The reason is actually pretty simple: Goggins doesn’t want to think of the world or the characters of Fallout as elements of a game.
“All of a sudden, I’m looking at this world from a very different perspective, and as something on a screen in which I am an avatar in. I don’t believe that I’m an avatar. I believe The Ghoul exists in the world. I believe that Cooper Howard exists in the world.” he said.
“The best way that I can serve this world and serve the fans of this game, I think, is to go to work every single day and believe the circumstances that I’m presented with,” Goggins said.



Makes perfect sense from the perspective of an actor.
They want their performance to come naturally and with the direction of the writers/directors.
Playing the games can make an actor subconsciously act how they think would fit the games rather than how would fit their specific character.
And also I assume it’d take probably a few hundred hours to go through every single game which like… I don’t think anyone would expect him to do ~200 hours of research for his character in White Lotus, so I don’t see why this should be any different really.
Understandable, but he might never know the glory that is fisto, which makes me sad.
I’m sure, if he goes to them, convention goers are more than happy to let him know.
