Please don't get me wrong but waiting 20min by looking into the screen and have wait those 20 minutes until something can be done (like for example start findind, tracking or engaging targets) isn't it too much for most players to bear?? I would say that something like this would detract 99,999% of players and potential players since even if this sim is as realistic as possible in the end this is still a computer game (and therefore "compromises" must always be made).
I ask that if this kind of feature are to be implemented that at least make it "optional" (selectable of not in the options menu). Again, please don't get me wrong... 25min is the time when the ready to launch missile gyroscopes are overheated, and had to put on cooling state (cannot be launched).
Playability is also constantly considered, while trying to do it as realistic as possible.
