Good simulation but faulty implementation

Following numerous accolades as found on the net, I was expecting a perfect simulator and it's far from being the case.
This is a game as much as FSX but less beautiful, less complete (no real missions) and less rich. The world is not modeled at all realistic (trees around Paris lol) and aircraft are poor. We do not understand why so many for so little DVD.
Addons must pay to complete the game but they are worth much for a result not at all realistic. It is far from a community like FSX which is nevertheless very old.
