I'm excited about VR coming to WWI flight simulation, myself! Other than some potential interest in Elite:Dangerous, up until the announcement of Flying Circus there was not a VR game that caught my enthusiasm and so had not invested in the hardware required for VR.
That's the truth, "Every takeoff and especially every landing is an adventure that can easily end in disaster", I get a real sense of accomplishment just taking off and landing successfully in Rise of Flight!
In the current sale I had picked up the Gotha G.V bomber, which I then struggled with. Checking the description in the "Newcomer's Multiplayer Plane Buying Guide 2.0" thread, I saw it was not just me ... "very demanding but rewarding bomber to fly", "Dangerous to fly, requires fine handling (autolevel helps a lot)", "Dangerous to land, poor ground control".
I never did try Wings Over Flanders Fields, not already owning a copy of Microsoft Combat Flight Simulator 3, and it being single player only, I didn't feel enough interest to pursue acquiring a copy. While I'm like the majority of folks that primarily play single player, I also like the option of participating in the multi-player servers, especially for the special events, if I so choose, and my understanding is that Rise of Flight then becomes basically the only option.
I have not yet tried Pat Wilson's Campaign Generator, which I gather is what folks have migrated to for their single player campaign enjoyment. I plan on exploring it in the near future, especially since his primary focus with the continued development is the IL-2 series, so the experience with it in RoF should carry directly over to Flying Circus. My understanding is that Pat Wilson does receive some compensation from the IL-2 studio for his work, which gives me confidence that he has access to the developers for at least answers where needed for the continued development of his Campaign Generator.
