I still play Rise of Flight regularly, though almost exclusively in the offline career mode. Their lack of decent online arenas and the boredom of facing the same two or three enemy pilots every time you go up in the online play got old very quickly.
And I tried the P-51 on his DCS account. Hated it, by the time I was done (about an hour), I had no desire to even try it again. He showed my his A-10 and MiG trying to get me to give it a go with jets, but if I wanted to spend all of my time flipping switches, adjusting knobs and staring at MFDs, I'd have just joined the Air Force.
