I have just recently purchased WOFF, and after my little campaign mission it deserves all of the good reviews it got, I am stunned. It is brilliant. Its really good to be able to use actual tactics to shoot down the AI, I had to drag and bag a Halberstadt D model scout in my SE5, I could not turn with him. I have never had to do this with AI before in other sims, that was generally left for online servers in the old il2 1946 days on warbirds of prey in my FW190D9.
Anyway brilliant experience, well done to all who developed and contributed to this sim
