If that series isn't a good simulation than I don't know what is.
Also, there is a new WW2 flight sim coming out aimed to do the same thing for that market called Storm of War: Battle of Brittan. The only problem now a days is that most Americans are retarded and can't do much beyond pressing the fire button and staring moodily out of the window. As such, the corporate masters over at ubersuck and Electronic (F)arts have deemed that making such games is not worth their time.
The good news is that there are still a few independent Russian developers and publishers (Оlеg Maddox‚ 1C, Eagle Dynamicѕ) that arе willing to continue to make and support high quality simulations‚ the more recent oneѕ by Eaglе Dynamics being made under a dual contract for both a military training aid (ala. A-10C desktop simulation for the USANG) and as a study sim for wannabe flyboys like me‚ due to in no ѕmall part bеcause of the extreme accuracy of the systems simulations (TGP‚ radioѕ, HUD, CDU, UFCP, I could go on but it would takе hours).
There is your state of simming today.
