Maybe a bit of it has to do with people working with what they know - For example: I'm introverted and drawing from woodsy/naturey experiences and so I'm trying to create that same vibe based on my own experiences. I've also been in warzones and think we need a lot more embodied notgames exploring themes relating to them.
Slave of God is a great example of how we can use the personal to convey the cacophonous and alienating intensity of certain experiences. I very much want to explore the role of city/rural with loud/quiet and some of the literature around designing sounds for spaces.
