It'll work great James, I've been flying this since it came out. It's a truly incredible update to Falcon, but you need the original Falcon 4.0 CD to get it to work, there ARE workarounds to this, but it's a huge PITA. I've found this latest BRS update to be the best variant of the Falcon series period. As good as Allied Force is/was and the same with FreeFalcon...well this just blows them all out of the water. The documents are frustrating for new players, as they assume you are familiar with how everything works, especially the avionics from past versions like FF and AF, and the basics are glossed over. You absolutely need the manuals and docs from freefalcon and Allied force or you're be pretty screwed out of the gate. That said, after a couple days of familiarization with the systems, you'll be able to take full advantage of everything they have done with the new game. Hands down the best campaign ever devised, and the actual "sim" part of the game is as good as anything current like A10, flaming cliffs, or KA52 and so on.
For a free game it's hands down the biggest accomplishment in PC combat aviation simulations since...well Aces High was first introduced in my opinion.
