Do they really think they are going to tempt away any pilots currently flying the Il-2 series? Or the soon-to-be 'World of Planes' series?
I suppose if you are interested to learn how to operate this particular Bird then it's a no-brainer. Just do not even for a second think that any knowledge gained from IL-2 will mean that you can successfully complete a circuit in the Mustang - it's a wee bit frisky
Not Il-2: 1946, sure. And you are correct that the new engine (currently only with 'Cliffs of Dover') does not have a P-51, but the aircraft it DOES have, it certainly models in as much fidelity (every button and switch in the cockpit works) as any DCS game. So that series (next title being Eastern Front, and then...?) will handle this well.
And I guess that's the point.
We have IL-2: 1946, with it's follow-on series already started and promising this level of simulation fidelity in combat ('Cliffs of Dover'/'Battle of Moscow'/etc)
We have 'Wings of Prey' out already, and the soon to be 'World of Planes' for pilots that want slightly less realism, and are closer to 'casual combat sim' gamers.
We have FS-X for those who want a hardcore 'buttons/switches/navigation' experience and to 'just fly around'...
the entire planet and virtually all airports and navigation points therein.
What does this bring to the table? For previous DCS games, the answer was easy - 'combat simulation of modern aircraft'. For this, though...it seems any particular group who would be interested in it for any reason
already has a sim out there for them, that covers the topic better.
