Yes I've been enjoying it a lot for the past 2 years or so. Some observations: - The flight and engine models are mostly excellent, and they have been getting better if you compare early planes with later creations. The torque generated by rotating engines is modelled very well. The fact that they are all taildraggers requires some good landing skills. Forward slips feel very much like the real thing. The lack of many of those steam gauges that we are used to requires you to look out of the window a lot (well, they don't really have windows do they?). - The flight environment is modelled very well. Turbulent air feels realistic, clouds are not too bad, light effects are nice. The airstrips are bumpy which makes for some good taxiing; they come with grass as well. There's a mission editor that lets you create your own airfields which is good because the default ones are not densely populated; you might want to add some hangars, vehicles, triple-a's, and villages, to look it more realistic, and to give you more visual clues upon flare. Hint: create a mission with a lead plane so that you are his wingman, and try some formation flying... - Dogfighting is modelled very well. Having used CFSI and II, only when I started flying rof I realized how difficult it is to shoot down other planes. Also, even if you prefer the pilot's seat you may want to check out the turret gun, it'll make you realize how hard that job was. - Performance. Frame rates tend to be very good, on my system as good as with x-plane. After all at times I found it hard to return to x-plane, but rof covers a totally different flying context, seat-of-the-pants flying a hundred years ago. It is at real as it gets, but then I still want to simm in a contemporary flight environment, with navigational aids, instrument approaches, and ATC, so x-plane is just so much closer to what I would normally fly.
