Waiting my SHIV yet...
Probably goes same way than IL2 series, get Pacific Fighters when it came - install merged and play one career there. Then returned back to Eastern Front
So now you may ask why bother to bought it? Maybe I'm maniac... I have IL-2, IL-2FB, AEP, PF, IL-2FB+AEP+PF and IL-2 Sturmovik 1946
And now I'm back with SHIII with GWX and hooked
So my answer is no
