Diablo 2 Resurrected is doused in multiple in-game transactions- a proverbial wall of sales with exaggerated percentages to make players believe that the more they purchase you, the more money you save. This has been common practice on the mobile market for many years, however different the presentation may have appeared. You see it with D2R Items Genshin Impact's Genesis Crystal store, where buying huge amounts of currency will grant players an even larger amount of the same exact currency. Also, you can see it in the case of Lapis -the currency used in Final Fantasy Brave Exvius -it entices players by offering "bonus" currency that can go into the hundreds of thousands after purchasing packs worth more than $100.
"A most common strategy used in mobile games or any other game using microtransactions, is to make the money," an anonymous employee who works in the mobile gaming industry told me recently. "Like, if I spent $1, I may get two types of currencies (gold and jewels for instance). This helps conceal what the actual value of the cash spent as there's no one-to-1 conversion. Furthermore, we purposefully place less favorable deals in front of others to make other deals look more lucrative and make players believe they are smarter by saving out and taking advantage of the other deals."
"In the firm I worked working for, we had weekly events featuring unique prizes and were planned to allow players to [...] win it using rare in-game currency, which would let you get one of the major prizes. The designers also had to include other milestone prizes on top of the first prize, and that would normally require cash to be able to win the contest. Our most frequent milestones and measures to determine if an event did well is of course how much people spent. We did measure sentiment, but I'm guessing that the higher-ups were always more concerned about whether the event made people spend."
Real-money transactions aren't novel in any way by any stretch of the imagination. Diablo 2 Resurrected didn't pioneer them however it would be not honest to state that as actual fact. This action-RPG by Blizzard isn't really the primary source, but it is instead it's the most terrible amalgamation of free mobile and PC games. With two different Battle Passes, both with distinct rewards unique to a particular character (and not part of your overall roster) and a myriad of various currencies for the average player to keep D2 Resurrected Ladder Items track of Diablo 2 Resurrected's financial system reads like a giant mobile market.
