I felt the same. I came late to Zero Dawn playing it 5 years after it came out. My first Zelda was the original Zelda (I was 7 when it came out) and Zero Dawn is the closest I ever came to that same feeling as an adult. I don't know the siblings comments are on about—I usually don't really care about the story, though I found myself super curious to find out what was going on the whole time and worried less about what kind of person Aloy was.
