Video Games are always moving closer to being an experience as compelling as any experience you could have in real life, and perhaps in some instances be more compelling, given the nature of fiction. Because of this, do you think that one day, music in games will be entirely unnecessary? You can already see this happening in some cases.
Look at any Fallout game for instance, whether it be the originals or the two newest games, they all have zero in-game music outside of an ambient soundtrack and a few radio stations. They don't have any proper score, I'd say that 95% of the soundscape is in-universe (including the radio stations of course), and you don't even notice the other 5% unless you pay attention. I think this works to its benefit, but it could be something unique to the universe that makes it work.
My point is that music can add to the mood and greatly improve the experience of watching a movie or play, but I'm not entirely sure that it will always be true for something as already inherently as visceral as video games. What do you think?
EDIT: Yes, I know that it's pretty much necessary at the moment, but I'm talking about the future, when video games are more like virtual reality than anything else.
