Have you heard of VATSIM? I'm a member. You fly with real people acting as air traffic control. You talk to ground for request to depart from the gate, taxi to the runway, take off, transition to the control tower, transition to departure, all the way to landing and contacting tower. Emergencies are supported so long as ATC allows it.
I don't know gentleman. I have been simming for 6 years on an average of 2 hours a day each and every day which is a minimum of 4,380 hours most of that flying a PMDG 737 NG. I bet, just bet that if I got the opportunity to jump into a real life 737 NG simulator I could take off and land. Just give me weight and fuel inputs for the FMC so I know VREF for take off and land. I have seen kids in simulators on YouTube fly in simulators. It's all about experience. It's like riding a bike once you do it so many times it becomes second nature. So making quick second decisions shouldn't be a problem. Experience, experience, experience!
Not trying to brag, but there are some pretty smart people out there who sim and have the capabilities to fly a real life simulator.
I made this video a while back with no fancy add-ons. DIA was one of the few upgrades I installed at the time. Audio is kinda crappy due to Windows Movie Maker that was used.
