Note I specifically referred to the regular IL-2, which uses a detailed hit point system and does have many more canned aspects to it's flight model than WW2OL.
Much of that was improved in IL-2: FB.
However, in IL-2 the flashy sounds and graphics do such a good job of immersing you into the cockpit that they could have an arcade flight model and it would still impress people.
Unfortunately nothing short of a Cray can handle a full physics model at this time. Oleg Maddox had to drop many modules from his Il2 physics model because no home CPU could come even close to coping with the data. FB had a few more included, but still far short of the full complement.
I never said WW2OL could match miltary level simulators.
But it's still the most advanced in it's field. And no, IL-2 is not in WW2OL's field, WW2OL could do everything IL-2 does and more if they didn't have to worry about combined air, sea, and land in a seamless scale model of europe with thousands of players.
