I bought Falcon 4.0 Allied Force yesterday, and while I wait for it to arrive I'm doing some research about it.
I came upon this website and am wondering if anybody knows if it's compatible with F4AF.

It says that it is for Falcon 4.0, but nothing about F4AF.

Thanks!

I got Falcon4 and Allied Force when they first came out and have done Free Falcon as well.  Free Falcon is a whole different ball of wax from Allied Force. Basically the same sim, but different developers. I haven't done any of them for a while (after sooooo many years, it loses some of the thrill). I am unsure what stage AF is at in its development right now, but Free Falcon is continually in development, and they have recently released a new version--5.5 I think. If you go to their site, it is a free download. Quite a complex sim, and you can have tons of fun with it. Pretty good support in the forums too. Oh, and AF and FF are both stand-alone, so you don't need the original Falcon4 anymore like you used to, to run FF.
