While it is playable, very greedy, but he has no purpose.
For me and for twenty years, with games like Red Baron, FS3 combat simulators and other Lutfwaffe control whether planes, boats or tractors ... The scenario should provide finality, even a simple pinball proposes to score and be the # 1!
In Cliffs Of Dover, no, no purpose except to steal, enjoy the sights, shoot down planes and go to the field to start .... until the end of the game .... sad to invest as much work development for so little.
From my point of view a real simulator must offer a real career management with possibly a selection via a drive, to be transferred to a flight, rather than another, flying on an airplane type, rather than another ( as in IL2), then over the assignment and provided to succeed, get promotions that can apply for a transfer to steal another squadron (as in Red Baron), with possibly another type of aircraft, see the order squadron, choosing his wingman, its armament, prioritize goals made in ... just have a purpose, like finished his career with all the medals, promotions, stealing the best aircraft and that in each camp. HERE THAT NOTHING.
