In the first few Zelda games, is Link supposed to be an adult or a kid?
Like in the first Zelda for the NES, I’ve always thought of him as a kid. In the second one, Adventure of Link, I imagine he’s an adult. Then in A Link to the Past, I picture him as a kid again. Obviously, you can’t really tell like you can in the 3d ones.
I’ve always imagined him as a teen rather then an adult, somewhere from 16 to 20. in the first few games, he is probably a kid or young teen.
