It could be even weirder. We might be playing video games that are essentially built from the ground up by and for the individual gamer, such that the concept of a "game", let alone the same game, doesn't even make sense. Same for what we have called movies and TV for the last 100 years.
You can already go and generate a book to read or a song to listen to, no one does this, I don't know why you expect it to be different with video games. People want to consume art, they don't want to make it.
You can't just remove the societal/cultural aspects of art without neutering its emotional appeal and impact. Ripping all humanity of out movies/video games is not going to result in higher quality art.
