wet-willie:The biggest issue in my opinion is the control feel and response. I have used X-plane for quit a few years. It has the correct aerodynamic response and is one of only two flight sim software packages I have ever used which did, IMO. The other is an old program called Chuck Yeager's Air Combat. It had amazing flight characteristics in every aircraft that I flew, but it is old and the graphics were pretty basic.

Chuck Yeager's Air Combat. Aaahhh now that brings back good memories! I also thought it had amazing graphics and physics...until I played it again recently using an emulator on my current system. I had trouble making out the runway, the graphics were so pixely. I nostalgically remembered the amazing dithered horizon (one of the first sims to feature this) and today it looks terrible of course. But a very advanced and fun game at the time, something modern sims have trouble managing (being complex and advanced AND still fun). I loved flying the Mig. And a picture of Chuck would appear and he would shout "check your six"....ahhh classic.
Cheetah, I admit I unfortunately don't have time anymore for reading bible size manuals either, but I do like them. Instead I frequently use the trial and error technique (i.e. "what does this button do" or "now where were those flaps again"...) something you can do in sims, not in the real life.
In diving I do read the manual and try and avoid the trial by error...
