I was borderline addicted to D2 during my high school and beyond years. I'd literally do nothing but play D2 for a solid 4-5 year period.
Then I discovered POE, this was back in the alpha days, I created the wiki (which eventually got sold to Curse which is another story) and played PoE pretty muich daily for a few years.
I'm entirely burnt out now, but just hearing the D2 music has got me in the mood to play it again.
