One area where sim vs game becomes apparent is in the gunnery. At least for me. Maybe it's because I played AH a lot for a few years, maybe not, but I can hit a turning target at 800 yards consistently in AH. I cannot do that in DCS. This reminds of a story my brother told me when he was flying the Apache at a joint Army/Air Force exercise at the Nellis ranges. At the time the Air Force was trying to give the A-10 to the Army. Anyhow the Apaches were suppressing the target area with fire as F-16s were coming in to hit the target. The Apaches stopped shooting when the F-16s got in close. The Vipers told them, don't stop shooting, it's a big sky.
