If I had to identify a game that radically changed the public perception of videogames, that would probably be The Legend of Zelda.
It was one of the earliest examples of modern gaming, changing the game design from an “arcade” standard to something that was more suited for home consoles.
No one said Journey, but it’s one of the best immersive games that let you wander in really cool environments. Might be a little frightening in some parts but under your supervision it should be fine
