A game that was a game-changer for me when I was a kid was Myst. First of all, it was ridiculously atmospheric and creepy, and the environments really drew me in. But I also loved the story, and it was what got me interested in cosmology and metaphysics and the concept of a multiverse. Iโd say it was among my first all-out obsessions growing up. It was all I thought and talked about for like a year.
