TrueKill, dont bother.  It's really a crappy game.  Unless you are a modern air combat freak and know the actual terminology for navigation and know how to operate the plane, its not a good buy.  Bought it myself thinking it would be somewhat easy to fly and such.  It's extremely complicated.  You would probably need a good few hours just reading the manual and memorizing key's just to fly, let alone fighting.  Also there are only 8 aircraft in the whole game so its a very limited selection. 
Did I mention it takes up a sh## load of memory usage?  You need atleast an ATI 9600XT just to play the game on low settings. 
Don't get me wrong.  It may be a sweet game if you really have a great deal of knowledge about the planes, but otherwise I would turn it down.
Very nice movie.  It was definitely a treat to view. I give it a 9/10
