I'm digging the idea of spacial audio, but for my 2 cents I do not enjoy the interface. It seems to encourage a lot of loud geocities/MySpace-era visuals.

I'd be interested in a top-down 2D space (like a million games, but just for example: Among Us) with spatial audio. That'd be pretty interesting.

Judging by what my kids like to play, I could see a place in the market for a 2D virtual world with this kind of feature. Create your own spaces, "decorate" them, plus spatial audio. That sounds like a winning combo.
