I did VATSIM briefly, years ago (pilot, not ATC). Never a virtual airline per se, but I did enjoy the Level-D 767! Flight simulation has been a favorite hobby of mine for over three decades (since my teen years). My current obsession is the recently released DCS F/A-18C (early access) in VR.
Such an incredible work of art sitting in the virtual cockpit of the Hornet!
Just about have the startup procedure memorized, now I'm trying to rap my head around Case-1 recoveries aboard the Stennis CVN-74, Aerial refueling with my wingman on the KC-130, which is an absolute blast, especially in VR! I have a complete HOTAS setup with rudder pedals and I'm using a neat little program called Voice Attack to give verbal commands to ground crew, wingmen, the limited ATC in the game, as well as comms with the tanker. It works incredibly well. No need to peek underneath the Oculus Rift to hunt for the keyboard to bring up a menu for comms. I might post a video showing this feature in action.
Haven't even attempted weapons deployment yet, having too much fun just learning to fly this thing.
This is the most detailed and the most challenging flight simulator model that I've ever tried. I'm hooked.

My daughter (who has flown with me several times in GA, as well as travelled on the airlines) once commented on how flying is a passion for me, but to her it's just a means of transportation. Haha
