I voted OFF,
Like JM I wish I had time to fully play it, immerse myself into the campaigns and all the squadron life as it is, but I voted for OFF mainly because it has something developers in fact don't give a s**t about -the Single Player experience. ROF, I had to wait almost TWO years for all the shift and Campaign to arrive, Cliffs of (my) Depression, that's a joke in the face...
FE2 is another nice one with good graphics delivered without ROF requirements, and is mean to be modded (like all TW sims in fact...)
ROF, I have a problem with this title, at the beginning in mid-2009 I was soo pissed at the devs and the online DRM, now it's past, but still to me it's more of a FM/DM tech demo than a real flight simulator, whose aim is not to only (very accurately I admit that) depict the single plane one's flying but whole war environment "going on" around
