I just purchased X-Plane 10/11 to get ready to try it with FlyInside. I've spent a couple of hours flying it, and I can say, without a shadow of a doubt, that I would rather go to the dentist and have a root canal than be forced to fly another minute of a non-VR flight sim!
With FlyInside coming to X-Plane, and Dovetail's Flight Sim coming out soon (???), I have decided to take an addon sabbatical. I'm just going to have to be happy with what I have for now.
