42. I never played Diablo. IDK why. I played all of the Warcrafts. I watched a friend playing Diablo 2 and it seemed cool, I just never got around to it. Of course, that was around the time I had 3 rugrats who demanded constant attention, so I didn't get much gaming in during those years anyway.
After a long time playing WoW, I finally burned out and left last year. I've been playing a lot of other games in the meantime, but I was looking for something new, and felt it was time to give this a shot.
Yes, I know it's nothing like WoW. That's part of the appeal. I loved those years, but the politics and herding cats wore me down over time. This game? I can play socially when I want. And I can play solo when I want. Win/win.
I'm not surprised the average age is north of 20. I'm surprised it isn't north of 30 considering the following from D2.
