After being unimpressed with the early betas, I've been sitting on the side lines waiting for the final release before I pass judgement.
Actually, I'm starting to like what I hear about the enhanced engine management, more challenging ground and flight modelling, and the elimination of the 1000 yd kills.
Pretty graphics are nice, but the crucial elements of any sim are the physics and the gameplay. If AH2 concentrates on the latter two, it will attract many of the old WB/AW crowd, and possibly bring back all the old jaded AH'ers.
