I've been flying RoF for at least a couple of years now in my limited free time. I pre-ordered BOS because of the tremendous amount of faith I have in 777. I pre-ordered CoD, as well, and only 777's involvement could have convinced me to do so again.
As others have said, these guys have skills. Overall, RoF is possibly the most-impressive piece of gaming software this aging gamer has ever owned, and the company has done nothing but conduct itself honorably during my time as one of their happy customers.
I lean more toward WWI myself when it comes to aviation, but I'm keeoing an open mind and looking forward to my premium pre-order.
