I think the notable thing for me is that usually, when I beat a game or lose interest, I stop playing. With Destiny, I was starting to lose interest, but I kept playing. Kept grinding. It used to be fun, but after the DLC released, it felt Sisyphean. But I kept playing. After beating Crota in week 1, and endlessly running Eris bounties, releveling exotics, and doing the urn bounties for all three characters, I couldn't do it anymore. This is the only game I've ever played that kept me playing after it stopped being fun, after it started feeling like work. And I think a lot of people are in the same boat as me.
