I flew many 'real time' instrument flights to Europe, Asia, Australia, et al.
I've been meaning to get back into flight simulation. sstrams and I discussed this not too long back. I almost pulled the trigger then. I think the two top rated ones are MS Flight Simulator and X Plane. X plane supposedly being a little more realistic and technically accurate and MS Flight Simulator having better graphics for a more realistic look. I've spent HOURS trying to decide between the two but I probably lean MS Flight Simulator. - JamesJM
