I got this to tide me over until it releases:
The Little Big Butt Book : Hanson, Dian: Amazon.co.uk: Books

Almost same playtime here for me, maybe even approaching 2500 hours, except most of that was on my own, I can't imagine how many hours if there was always someone else there to play with. I used to play with a South African couple with VC but then one day they had a massive domestic argument over something non game-related and it was awkward and after a bit I was like... uhhh shall we go do a rift? They never came online again after that session lol.
Then another woman I played with was in Israel during a more intense period of rocket attacks, she went offline one day and never came back online

I do think Diablo 3 was just an endless game she was playing to take her mind off it and she just stopped playing one day rather than a more sad end to the story than you can imagine
