This event is every January! And 2017 was the first time because of the Anniversary of Diablo 1. That's why the graphics look so oldschool. I just restarted to play Diablo 3 because of this event. I missed it last year and wanted all achievements to be done. Just took me around some hours but it was fun. Starting to play my Necro again! Do you play Season or Off-Season? SC or HC?
