!SimHQ.com - Air Combat Zone - Review: Falcon 4.0: Allied Force - Part 1. When I first got a PC, I played Falcon 3.0 for hours and hours. I just loved that simulation. And F-15 Strike Eagle and Harpoon. These kinds of realistic simulations fell out of favor when Doom and its ilk came out. I still have a soft spot and there are all kinds of sites on the net that still support Falcon and now a publisher has actually brought the game back.
