Vladko: thank you for positive attitude about flightsim. that is not always seen, but we are happy for every real pilot that is willing to share his experience for our benefit. I have a little mailing list of pilots that I can discuss real-life aviation and its implications for flightsim, lately we have discussed the TCX Manchester incident. Mind if I shoot you a message from time to time?
Notso Fantastic: Try to think of this as a hobby. Some people work their backs of in the garden, some knit, some build models. We "fly" the simulator.
Some do it because they wanted to fly for real, but couldnt. Some fly it with aims of someday moving on to real aviation. Some just for fun of it.
That said, PMDG is the NG simulation. Now I have no real experience, but I am told that landing a CL and landing an NG is somewhat different. Also, are you talking NGX or the original FS2002/4 NG? Leaps of advance between those.
papa600: I definitely agree for FS2004, although I am amazed by the NGX. You should try it if you have NGX
