Battle.net has more on the 20th anniversary of Diablo, as the original version of the action/RPG was first released on December 31, 1996. They will be launching their previously announced celebrations across various game soon, and on the meantime, offer a retrospective, including this video with a look back. Here's what they have to say:

December 31 marks the official twentieth anniversary of the original Diablo!

We’ll soon be launching Patch 2.4.3, which includes an anniversary event filled to the brim with fun callbacks to the game that started it all. Before we kick off the in-game celebration, we wanted to look back at some of our favorite memories from Sanctuary.

For some, that means late nights doing Baal runs, getting that last Conquest in Seasons, or finally getting an Archangel’s Staff of the Apocalypse to drop. Others may never forget the terror of encountering the Butcher for the first time, gruelingly defeating Duriel, or getting killed by Malthael (and then returning the favor). . . .

Whether you first played Diablo two days or two decades ago, we want to thank you for bringing your unrelenting passion to the franchise. Your support and feedback continue to help us shape the world of Sanctuary, and it’s a true honor and privilege to walk alongside you on this journey.

As the hour of Diablo’s first reign of terror approaches, we’ll be pouring a glass of our favorite brew in his honor. We hope you do the same, and want to again express how thankful we are for your support.

May your loot be Legendary, and may you forever be victorious in battle. Cheers, nephalem!
