Pandanator 2

1. A variety of joysticks are available for configuring, as well as throttle quadrants and other things you may want to hook up.
 
2. Autogen is much better than default FSX. Sky is also better, especially on some weather themes, but not all.
 
3. In the 2 areas of the world that are included (Alaska and Hawaii) a variety of landmarks are modeled and shown in Flight.
 
4. Airports are rather well represented in comparison to default FSX. 
 
5. Several aircraft are included, free ones are the Boeing PT-17 Stearman and the Icon A5. Purchasable ones include the P-40 Warhawk, A6M2 Zero, RV-6A, and Carbon Cub.
 
6. It's single class piston aircraft. Overall not very fast, good for low/slow flying.
 
7. Imagination  :Idea: I've heard that GPlan is compatible with Flight, although I can't personally confirm this.
 
8. At this point in time, no, there are no 3rd party aircraft. However, there are a wide variety of different liveries for existing aircraft. 
 
9. Many aircraft included in Flight are still flying. I think the one you saw was the Icon A5, which is a sports aircraft rather new to the aviation world. Carbon Cubs and RV-6s still fly, as do some warbirds in airshows.
 
10. I'll take performance as meaning how is the game engine. Personally i find it very good next to FSX, performs well on medium-high graphics on my extremely sub-par computer. 
 
Bonus. I was extremely happy with my decision. However the one thing that kind of killed the experience was the cancellation of production. That was a real downer. However I still fly now and then.
