FSX/P3D. I won't lie. The CLS DC-10 looks really good as far as visuals are concerned. But as for systems, I would not expect much. You might want to go with the DC-10's competitor: the L-1011 by CaptainSim if you want to actually do some work. That said, the community is desperate for a DC-10 so I wouldn't be surprised if a few of you NGX cats break down and purchase a copy. After all, it's the legendary DC-10. A sentimental aircraft even to myself. It was my very first widebody experience. I remember it like it was yesterday. Autumn 1993. AA ORD-LAX. They were projecting The Fugitive with Harrison Ford on a screen lowered before the bulkhead which seemed almost a football field away. I was also too short to see above the seat ahead of me so I had to just plug into the headphone jack and listen whilst enjoying my in-flight meal of cold cardboard chicken. Ahhh.... The good old days. My second DC-10 experience was jumpseating aboard a FedEx variant MEM-LAX right on the flight deck. It was also my final flight on the type and forever cemented in my heart as one of my all time favorite aircraft. Shit... looks i'm buying it... Christmas? Well see.
