“Recent anime works will show things like a level-up gauge that appears when characters tap the air, even though there’s no in-setting reason for them to have a personal interface like that. I may just be getting old, but it really makes me wonder: ‘What is going on here?’ It just doesn’t work for me.“

My idea on what’s going on here is, people find it impossible to imagine what is entirely alien to them. Fiction uses various tricks to bridge this gap for its audience; by describing familiar experiences in a fantastical context, it draws you into its imagined reality. But for people who exercise little actual agency in their real lives, don’t go outside much, and play a lot of videogames, the traditional material probably isn’t stuff they can relate to as well as people in the past could. A fictional world that has the mechanics of a videogame is a natural direction to go because it will be easier for modern people to imagine than a fictional world where nobody uses phones or computers.
