If you're looking for a WW2 flight sim, get this, as it has everything you want... Once you get the AAA mod, you will even be able to fly the enola gay and boxcar and drop nuclear bombs. The only complaint I have is it's pretty much only Eastern Front, no real western front stuff...
This has all of the IL-2 series in it though, so go for it, it's the most complete in aircraft listing to date...
