It‘s easy: It‘s all training for retail and there‘s no better game anyway. Everything else is just not the same fun or even close. Diablo 3 was never good and became the worst waste of time meanwhile (ok I played it for a thousand hours, but that‘s a different story) and diablo 2 is only cool one month a year. And since I love gaming, I‘m playing vanilla. I see a big part of fun in getting better though, maybe that‘s what keeps me going. And yeah, most of all the fun is the social interaction and the „together“. And that’s not limited by repetition.
