I pretty much agree with the original poster and have a lot of empathy with the point about not wanting it to feel like a 2nd job, which it can.
I used to fly BMS and drop back into it for the odd flight but soon give up because VR has really been a big game changer for me. I have flown very rarely online with a few really nice people and these were great experiences but the sessions are just far too long for me to commit to because of family, jobs and all the other life stuff.
It still remains a big hole that I can't seem to fill with something I really love doing and have been doing for over 20 years.
I agree with the other point that the answer is a dynamic campaign both for single player and multiplayer respectively.
