Diablo 3

I've been thinking more and more about the question -- "Is Diablo 4 an MMO?" -- since I currently play World of Warcraft, am pretty heavily invested in Diablo 3, was into Diablo Immortal for a couple of months there, and was just utterly charmed by the open beta for Diablo 4.

There's an argument that the art direction of Diablo 3 was too 'light' -- an argument I find strange because there are still mounds of corpses, blood and gore strewn across walls and floors, and whole hosts of demons exploding out of every corner to destroy and consume all things.

The spellcaster archetype has always existed in the Diablo series, but there are a few more differences between Diablo 4 Sorcerers and Diablo 3 Wizards than just the name.

Blood Shards are not a new inclusion in Diablo 3; they've been a necessary currency for the franchise's current form of item gambling through the merchant Kadala, found near the Nephalem Obelisk in every Act.

Puzzle Rings have been used in Diablo 3 to open portals to Greed's realm since patch 2.3.0.

Diablo 3 Season 28: Rites of Sanctuary underway and introduced the Altar of Rites to New Tristram, which grants powerful (account-wide) boons -- but with a price.

Season 28 of Diablo 3 adds some gameplay twists befitting the Rites of Sanctuary Season theme -- including ritual sacrifice on the Altar of Rites of expensive items, like the Staff of Herding.

Diablo 3 Season 28: Rites of Sanctuary brought to an incredible theme to the table with the Altar of Rites where you can make sacrifices to unlock immense power.

Diablo 3 Season 28: Rites of Sanctuary is up and running with the Altar of Rites, which combines previous themes, item buffs, and new boosts into one big talent tree, letting you "buy" new abilities by sacrificing things like blood shards or crafting materials.

While your exact definition may differ, to me, a progression system is any system in a game that allows you to accomplish a goal and gain something that feels rewarding.
