THIS "GAME" already exists. DCS...they do still have what you could call "GPS" navigation for WW2. GAWD, I would hate to see it with the tools of THEN

"You mean, we have to know Math? MOMMY!!!! I am lost!!!"

They have done some NICE work in their WW2 plane sets though. Tweaks in their NEED FOR ENGINE management too sustain operation of engines. Especially in their Spit MK9...was hard,in the early days, to do ANY maneuver with slightest bit of vertical element...without blowing engine

The PONY is pretty SWEET now as well...UNLESS you like running WEP

SO...MORAL of THIS STORY...Careful what you wish for
