With every new release, records are broken.
Diablo 4 is shaping to become what many Chinese/Korean top down MMORPGs wanted to be, bu ultimately failed. Games like MU Online, Ark and Lineage Eternal.
Diablo will again set the bar. And it will reign on top of the ARPG list until Diablo 5 comes out.
And nothing will come close to it. I look forward to Path of Exile 2, but it being F2P game it's already fighting an uphill battle.
