If nothing else, DCS World can be used to make some awesome videos. Who could have imagined how far PC graphics would come so quickly and how much time, effort, and money people would put into the models and textures to achieve such realistic and beautiful results? I prefer flight modeling and systems modeling detail/accuracy over graphics, but if I can have everything, I will take it all! As Queen once sang, I want it all and I want it now! I can't wait to get the F-4E. But one hole in the US lineup is the F-15. DCS now has very detailed modules for the rest of the "teen" series. The current F-15C is extremely fun to fly because the flight model is comparable to the other modules, but the Flaming Cliffs simple avionics can't compare to using fully modeled clickable cockpits in VR.
I know most people want the latest best aircraft and would rather have an F-22 or F-35. But I would rather have the early IOC versions of the F-14A, F-15A, F-16A, and F/A-18A as these were the state of the art aircraft I grew up with that replaced my beloved F-4 and they had quite a few ugly warts that make them more interesting to fly and fight: engine problems, radar and ECM issues, etc. Not to mention missiles that were at best marginally better than what we finished Vietnam with. Fortunately, Heatblur plans to provide the F-14A. But I doubt we will ever see any other early variants of the "teen" series.
