But the soundtracks have spread their influence beyond their sphere of origin. Yes, game music is different from movie soundtracks, but they both suffer from the same kind of ossification, the same allergy to form and meaning. And people hear this kind of music - a lot - and can't help but be influenced by it.
Games without music - well, for the games I play, they're far better that way. I turned the music off in Skyrim years ago, and never regretted it for a second. Minecraft ditto.
