I think FSX is great, it consumes majority of my flight time although if it wasn’t for the third party developers I would have probably forgotten of it’s existence.
I’ve read some comments from the real world airline pilots about the FSX and it appears to be a mixture of views where some say there is nothing like doing it for real others might say it’s good for IFR practice, but it’s not always clear what they fly in FSX and I couldn’t be arsed to ask.
No one has mentioned the VATSIM, perhaps the squawk is on standby.
