In the case of Diablo 2 Resurrected they use Legendary Crests (which can be purchased or earned) to increase the chances of a five-star gem showing up in endgame dungeons. Although it's not exactly traditional in its presentation (most gacha are performed by "rolling" in a limited-time banner) Players are engaged in the same kind of randomness similar to. In many ways this D2R Items, it's like the Diablo franchise was working towards these mechanisms since the beginning of its existence, such as Maddy Myers wrote a few weeks ago.

Diablo 2 Resurrected also, in the simplest terms, takes directly from an "feeding" technique that many Japanese, Korean, and Chinese mobile games have normalized for over 10 years. "Feeding" is the process of increasing the stats, attributes, or the rarity of an item by making duplicates of a drop. These duplicates are then fed to an item with similar rarity, which increases the overall stats of an item. Generally, five copies are required in order to max the character or item.

My first exposure to "feeding" was Fate/Grand Order, which was originally launched to Japan in July of 2015. It earned a total of 4 billion dollars in the world in 2019. In order to create a character that was the best that it can be, I needed to obtain copies of each. Then, when a particular banner came along I paid upward of 300 euros to purchase the 5-star character I'd wanted since the beginning of time. But I didn't get the duplicates I needed to realize this character's full potential. The rates for the most valuable 5-star characters now being around 1.1%, it's not a surprise that I failed to acquire a copy the character when I was engaging in this game (which I've since removed). As of the end of July, 2021 Fate/Grand Order was the seventh highest grossing mobile game of all time, putting it in front of Konami's Puzzle & Dragons, which also, I'm guessing, is also a gacha game.

In a GDC 2021 speech, Genshin Impact developer Hoyoverse (previously Mihoyo) outright admitted that the process of creating characters revolved around generating the maximum amount of capital from its fans. For example, the Raiden Shogun and Kokomi characters reruns that D2 Resurrected Ladder Items took place in March 2022 alone earned the company over $33 million in revenues.
