ED doesn’t make their own AC, and currently nothing is in production including bug fixes.
Compared to AH, DCS is extremely boring, less fights than almost empty AH arena which is still more fun.
Where are you getting this info? ED makes plenty of their own AC.... and bug fixes are constantly worked on and patched-in on a fairly consistent schedule over the last year or more... and before that it was always an ongoing thing.
As far as fun & excitement, that's totally subjective. AH used to be tons of fun, I got bored. When I was found myself doing 1 or 2 flights a month, I decided to throw in the towel. Nothing against AH, it just got dull. On the other hand, I wasn't excited at all about DCS (had it since LockOn was released) until I decided to put in the effort to really learn the A-10 around 2014. That's when things changed. It wasn't "easy" to learn the A-10, and I have so many modules now I'd have to do some refresher if I wanted to do anything other than fly around gunning stuff. I think that's key. DCS offers literal months of new challenges on a fairly regular basis. Learn something, get proficient, have fun with it, move to the next one.
This is how I think ED is able to sustain and (I know you don't believe it) grow. The DCS server numbers over the last few years shows growth, not loss. And Steam isn't a good indicator... ED (or someone?) hamstrung Steam-DCS from the beginning. Everyone I know (and lots I don't) have from day one tried to shoo people away from the Steam version and for good reason. It's almost like DCS agreed to allow Steam to sell the game just to shut them up.
So anyway, get your toejam fixed and get that Youboob vid out... and more. Nobody wants to see AH die. Get enough people back and I'd be back off & on too (Granted certain riffraff had been dispensed with).
