I love the flight dynamics of both Lock-On and the IL-2 offerings, but the worlds are so soul-less that I lose my enjoyment of them fairly quickly. They both give a fairly true to life sensation of flight (minus the bumps), but they feel so bland after a few missons.
Falcon 4.0 was the last modern air sim campaign to get my juices flowing, not
rookie friendly because of it's very accurate systems modeling, but a forgiving flight model. If F4 and LOMAC had a baby...I'd be a very happy camper.
All-in-all, I'd have to say IL-2:FB would be your best bet Vinda-Lou. One bit of advice I would give you is not to 'dumb' it down...go ahead and crank up all the realism and jump in with both feet. You'll save yourself the trouble of shedding bad habits later on down the line.
If you want to get into the theory of flight and of air combat, Tailspin's
is one of the best resources on the net. Send me a P.M. if you have any questions and I'm sure I can help you out.
