you can actually have a great feeling while flying
The first thing I noticed, aside from the looks, was that I could see and almost feel when I was skidding. The default scenery is so blurry I never noticed a skid unless I looked at the turn coordinator. Now I look over the edge of the window at the ground and I can see the plane skidding because the scenery moves under me. The ground elevation contours are much better and I can use dead reconing to get around which takes some of the hassle out of looking at the instruments.
The SIDs and STArs are an extra on one of the disks so I have all the departures and arrivals I need. But thats all on skyvector anyway.
