Oh I forgot ...auto-pilot and auto climb enabled for all planes in AH ?
That's not really the core of the issue. The core of the issue is flight modeling.
Autopilot, auto trim - hell, even trim for some planes that didn't have it - all these things exist in AH to make it just a tad more user friendly. The lack of proper engine management is also an example of this.
In terms of strict authenticity, IL2 is the better game, I agree (and I adore IL2's gunnery system).
However, in terms of "flight models" there is really no comparison for me. In AH, even the individual variants of the same A/C have clearly definable and noticeable characteristics.
In IL2, I do not find this to be the case. To me, in IL2, every plane feels, at its core, exactly the same. Each has the same exact reaction to inputs; differentiated only by airspeed.
The IL2 flight model is "bland." The one thing that HTC has done so well - and it's largely an unheralded achievement - is that they have given the player a real sense of weight and inertia. By comparison, IL2 planes all feel weightless to me.
While that may sound rather off-the-wall, I think its a key difference and its what many people cant quite put their finger on when they ask themselves what IL2's FM is lacking.
