Truth be told: I would not be surprised if I was near abandoning the game regardless.
I was grinding to try to get enough money to get a well equipped ASP. When I did, the toughest combat missions (Elite Anaconda kills) would become relatively easy (I could already do them in my Cobra, though my success rate was <100%). Since I'm aware of no faster way to make money without mining/trading, and since the max income rate on that is relatively low when we start discussing the hundreds of millions to equip an Anaconda, I think the grind would have gotten to me.
It's be big reason I don't play MMOs. God knows I don't mind slow-burn games (X3, Civ on large maps with slow pace, KSP); but repetition can get... repetitious.
In some games trading/mining have been fun to do; but picking up things in space is so slow in ED, and the trade routes so... generated in feel... that for me at least it hasn't been there. I know others have a different experience with those aspects. The tedium of FS travel is another thing that bogs down the game for me, especially with no auto-pilot and the tendency for the game to overshoot speeds.
As a child of the 80s, I grew up with video games that made you start over from the beginning when you died. That's hardly new. But I think what bothers me is that I have to start the *grind* over. If it were just plain fun to do, I wouldn't care.
