if you have room ,,get all three. Off is best once you get it set up because it has Flight and AI settings that allow you to hit some opponents once in a while. ,,ROf is very good but much more difficult to fly and survive, First Eagles 2 is just fun with lots of easy action and many planes. I have all three and fly them equally since modifying the ai in ROF so I am not just chasing my tail all the time.
