Warning! Headache ahead!
This game takes simulation to a whole new level. You pretty much need to know how to operate the real F-16 to even play this game. Of course it comes with a 800 page manual which will take you half your life-time to read, and of course you can't play the game unless you've read the manual or you'll be lost right away. Training sucks, no help just puts you in a situation and you have to find out how to play for your self.
So after you've got the game figured out it starts to get fun, dogfights are immersing, the campagins are dynamic and very nice, and the AI are very smart. One huge problem I had with the game were the graphics. Plane models are nice and terrain is average, but some of the animations are choppy. An example is when you eject from the plane the parachute comes out frame by frame, not smooth at all. Also the explosions and collisions look terrible. 2d cockpit is nice but blocky to look around in. 3d cockpit is easier too look around in but is not interactive or very nice looking.
Overall, if your looking for a realistic flight sim which acts the very same of a fighter jet and don't mind reading a 800 page manual you might consider buying this game. If you want a more fun experience with just enough realsim buy LO:MAC.
