Blizzard's focus with Diablo 4 and the franchise as a whole is player engagement, regardless of which title they choose.
Diablo 4's remarkable sales success, as Blizzard's fastest-selling game, underscores their commitment to long-term support. In a recent VGC interview, Rod Fergusson (series head) and Gavian Whishaw (executive producer) emphasized that sustained player interest across all Diablo games—from the original to Diablo 4—is a key victory. Fergusson highlighted Blizzard's policy of continued support for past titles, stating that players can still enjoy Diablo, Diablo 2, Diablo 2: Resurrected, and Diablo 3. The overarching goal is simply to keep players within the Blizzard gaming ecosystem.
Addressing concerns about Diablo 4's player count relative to previous installments, Fergusson clarified that player engagement across all titles is positive. The success of Diablo 2: Resurrected, a remaster of a 21-year-old game, exemplifies this. Blizzard's strategy isn't about actively shifting players from one game to another; instead, the focus is on creating compelling content that draws players to Diablo 4. Their commitment to supporting Diablo 3 and Diablo 2 demonstrates this approach.
The upcoming "Vessel of Hatred" expansion (October 8th) will significantly expand Diablo 4's content. This first expansion introduces a new region, Nahantu, brimming with new towns, dungeons, and ancient civilizations. The narrative continues the main campaign, focusing on the search for Neyrelle, leading players into an ancient jungle to confront Mephisto's machinations.
