I watched the video for this one night and bought it the next afternoon. It is amazing! Even when I've been on FSX all day, I still find it entertaining. As long as you find an airport with a lot of planes coming and going (Seoul-Incheon is the best, in my opinion), you can sit for hours (well, until your F-18 runs out of fuel) just shooting down enemy aircraft. I definitely recommend it.  ;D

One thing though, be sure to run FSX as administrator, or else the explosion effects won't be displayed.
