I am pretty hyped about playing d2 again with "Diablo 2 Resurrected". But I guess it's a bad sign that the most exciting thing they have going is a remake of a 20 year old past glory.
I'm way less excited for D2R. I was a hardcore Diablo 2 player, but the D2 endgame was spamming Diablo runs over and over, Cow Level farming, and one or two other things I've forgotten; not exactly dynamic content. Path of Exile has taken D2 game design to the next level, and the level after that, and even that game is aging (PoE2 is in the works). Obviously World of Warcraft Classic is the counter-example that will come to mind, but even original WoW still had plenty of content and grinds to do once you hit 60 (Booty Bay pirate hat, anyone?). Nothing in D2 will keep people around for more than a week or two once they've rediscovered how to play it.
Meanwhile it sounds like the Runic folks have also lost the taste for Diablo games. They made Hob, which looks cool but the basic story arc is not compatible with multiplayer (also PC only).
