Personal I would not buy any single civilian aircraft. If I would fly civil aircraft, I would use for eksembel FSX who is already based and specialize in this area.
I think it is wrong to mix these areas together, as it would undermine what DCS stands for and what the majority of us are here to do. In my eyes, it would be a huge mistake to do.
If you open up this area, there will always be battles between whatever the next flight must be civilian or military. And It's not because there are many companies here that are lining up to push new aircraft out the door. I my openion there are still many things that could be done better in the already platform we have today. Naval battles, more land-based battles with Combined Arms, just to name a few. Why make a uncompleted platform bigger and create more unhappy customers?
If you want to make something that looks like a little civilian, create flyable transport aircraft, refuel aircraft and reconnaissance, which is able to mark targets on the map.
