It seems simple, but Blizzard likely could have diminished a lot of that anger by padding Immortal's announcement out with the confirmation that a more traditional Diablo game was on the way, similar to how Bethesda, Microsoft, and Nintendo introduced their mobile titles. Diablo is an important, tentpole franchise for Blizzard.
"Diablo was supposed to be Blizzard's first shot on goal into the big global mobile game market", Jefferies analyst Timothy O'Shea wrote noting the criticism from Blizzard's PC fanbase.
Even with the controversial news of Diablo: Immortal Blizzard still confirmed Diablo 4 was in production but simply not ready to show at this year's Blizzcon. "We have many of our best developers now working on new mobile titles across all of our IPs".
Diablo Immortal is a sequel to Diablo II, and the prequel to Diablo III and the game has the main focus on the adventures of particular characters from the series between the two games. Not only that, but Brack said Blizzard has plans to support the game for a while after launch.
"For our diehard PC fans, we will say though, we still have multiple Diablo teams working on multiple unannounced Diablo projects". Mobile can compete for a hardcore gamer's attention. "With their incredible passion for Diablo and proven mobile expertise, the development team has spawned an ultra-responsive and breathtakingly lovely mobile game, and we can't wait for players to get their hands on it". I also think Diablo: Immortal has the potential to actually be a pretty neat mobile game, if undoubtedly not a replacement for a proper sequel.
GameSpot went hands-on with Diablo Immortal at BlizzCon, and editor Alessandro Fillari was surprisingly impressed by the game in this early stage.
The announcement of Diablo Immortal as a mobile exclusive has been the subject of much controversy over the last few days.
Part of the outcry from the community was due to resources being dedicated to a mobile title, despite much of the work coming from a partnership with developer NetEase.
