Glad you guys liked it, might make some more if I have time.
I played quite a bit of CFS 3 back in the day and I seem to recall that it wasn't nearly as moddable as IL-2 was. The mission editor was also much easier to use in IL-2 for creating new missions so that's really what sold IL-2 to the online players.
CFS3 has always been quite moddable (absolutely nothing you see or hear in the video is stock), but it was rushed out half-baked. Some saw the potential and stuck with modding it and have done some great things with it, but most saw the mess it was at the time and moved on to greener pastures.
