If you want to have “the MOST realistic sim possible”, go buy yourself a multi-million dollar full-motion simulator running on a mega-petaflop supercomputer. Or, you can cheap-out and get a personal Dream Aero cockpit.
As for me, I’m thrilled to have what I have - it’s a thousand times better than what I could have even begun to hope for.
However, (IMHO), this is a bit wide of the mark.
As far as I can tell, (from my very limited point of view), MSFS is doing everything anyone could possibly ask to be as inclusive as possible.
