Seeing as this forum has slowed down a little, here's some news...
Falcon 4.0 has been re-released as Falcon 4.0 Allied Force, with updated graphics, AI, avionics, a whole new theatre of operations AND the most awesomest dynamic campaign ever, i mean, it's really really really clever. So, the graphics remain poor, but forget your IL2's, LOMAC's, FS9's, Silent Hunter's and whatnot, this is a sim, and the others mentioned here are like toys in comparison.
