Have you given it a go with a REALLY nice VR setup? Dude it's incredible. I'm a private pilot who has friends who fly commercial and who've tried my setup at home. From a systems fidelity perspective and immersion, you can get quite close. They were all awestruck. Short of a Level D sim, they all agreed it's the best they had seen, and in certain respects even felt more immersive (lighting is a big one, since you have a lot more control over shadows and whatnot, compared to level D sims which usually end up having a disconnect with cockpit lighting and the outside, unless its a night flight).
