When cast as Ellie, one of the show's leads, Ramsey was advised not to play the hit video game as a reference point for the role.
"After my first audition, they asked me, 'Have you played it?' And I said, 'Nope,' and they said, 'Keep it that way,'" Ramsey told USA Today. "I did watch some of the gameplay on YouTube just to get a sense of it."
Ramsey started playing the first game after the show premiered on HBO.
"It's not as weird as I thought it'd be," Ramsey said on the "Happy, Sad, Confused" podcast in February, adding that she was playing on the game's easiest mode.
Her costar, Pedro Pascal, attempted to play the Naughty Dog video game despite being told to avoid it.
"My nephews were watching me play and eventually got tired of my inability to complete the level, so they took my controller from me," Pascal told IGN.
