I love this thread. My personal enjoyment of FSing derives from several areas:
1. I enjoy fiddling with the rig and FS tweaks to improve the experience, although this does get a bit tedious.
2. I "own" a virtual "charter company" and fly bizjets and a Boeing bizjet all over the western hemisphere. I make numerous flights to small airports in the West Indies during the Fall and Winter, and numerous flights into small airports in the NE US and Canada. Right now I am in the middle of a EU swing with stops in London, Dublin, Helsinki, Brussels and now down into Egypt where I overflew the pyramids (couldn't find the sphinx), and the Aswan dam, which was a disappointment. On the way back to the US I'll stop in France and Dublin as the jumping off spot. Very interesting and fun. I google earth all the fields I'll be stopping at to see how realistic FS is. For instance the great pyramids were spot on lat/long.
This is truly a great hobby.
