What would your dream flight sim game be like?

If you could describe any kind of flight sim game and it would come to life, irrespective of the resources required what would it be?
I was just curious about what people think, because with msfs2024 we have practically reached/almost reached a flight sim that's as real as it can get.
So what's next???
Something even more realistic than what we have, maybe something with more objectives, or maybe even a dystopian world flight sim?
