Actually andrea, I've played BoB:WOV and it is not arcade at all. The FM is different, in some ways echoing the experiences of those who flew planes of the era. Carborator engine in Hurri and Spit that has the tendency to cough and sputter under negative G's, different torque modelling, not what I'd call arcade at all.
Not questioning your request Sir, but I'd think if you have tried that sim you would not call it arcade. When I feel the need for 6DOF, I crank it up and it is a challenge to master. That and they have moved beyond the Rowan engine and developed their own game engine, ironically called Merlin. It'll do until BoB:SOW. Also- for the record, IL-2 is still my fav

with so many aircraft left for me to fly, let alone master.
Just my opinion.
