It must have been an extremely complex business, building an entirely new sim on the back of CFS3 like that. The clouds look amazing and very much like those found in "Battle of Britain II" (somebody said that the clouds in this make those in IL-2 look "sick" and I agree)
Looking at screenshots from WoFF, however, one shortcoming that seems to have been carried over from CFS3 is the gross distortion of aircraft models in external view, making screenshots difficult and restricted. Not an issue at all for gameplay, of course, but not a problem at all in either IL-2 or BoBII
I'm just carping now, I guess
