The game itself is very nicely done - even if some behaviors of Aircraft not correspond in the least reality. Unfortunately, very serious graphic bug causing some missions can not be completed - an example: at the airport in Odessa are the building in the middle of the runway (great!) - Many destinations are underwater or underground, and then can not be destroyed - it also happens that one of the ground receive suddenly jumps or one "off-beamed" is and where you suddenly is completely different!
If the graphics errors are eventually resolved - which I do not believe - there's also 5 star for the fun!
