I loved flying in DGS. I flew in some practice sessions, the beta, and all four frames, and I always looked forward to it. Like others have said, some might not really like the immersion and the work it takes to get formed up, rendezvous with other groups, waiting for orders from people who find out what's going on, and then the really fast action, it was really cool.
It was simply awesome looking around me and seeing 30+ friendly fighters in several groups within visual range of each other, and then seeing a gigantic mass of enemy bombers show up, and look around and see Ponies and P-38s everywhere. It was crazy, crazy stuff. The bomber group I helped attack in frame 4 was so tight, as some have said, you could hardly imagine fitting a playing card between them.
The only thing that saved my bacon this last frame when I attacked the bombers was that there were enough other Luftwaffe planes nearby that I wasn't always the guy a particular gunner was aiming at. Oh, and I'm glad to read that quote from Hornet and know I contributed to his "immersive" experience by taking out one of his B-17s. :-)
Personally, I can't wait for the next big scenario. I really look forward to it, and I'm sad that DGS is over with.
Thanks to all those who helped put it together, and thanks for the 300 or so pilots who showed up each Saturday and made it cool.
