I am enjoying the game and strangely it performs a lot better than ArmA2 (I haven't tried MP yet).
There are some valid points thought, I opened up the mission editor looking for at the aircraft and it was pretty weak. I see it as a "platform" and it definitely has a lot more potential then previous versions. I have been playing since OFP and although I am pretty ignorant when it comes to realism and the authenticity of weapons etc I think the game has a much bigger scope. If all else fails the game has one of the best mod communities out there.
