This is because many fans felt that the game’s announcement was a slap in the face, especially since many had been highly anticipating Diablo 4 (despite Blizzard tempering expectations), but it did not stop fans from voicing their displeasure publicly during the Q&A session, and on various online platforms and forums.
Turns out that Blizzard did not see this coming, according to executive producer and Blizzard co-founder Allen Adham who spoke to Kotaku during an interview at BlizzCon. According to Adham, “We know our audience here is passionately PC- and console-focused. We’ve also seen this before. We saw a similar response when we announced that we were bringing Diablo to console, and we saw a similar response to the announcement of Hearthstone.”
Diablo Immortals is not the first game to be met with such negative reactions. A couple of years ago when Activision announced Call of Duty: Infinite Warfare, it was met with massively negative feedback, but it still managed to be the top-selling console game of 2016. It is possible that players will have a change of heart once they get their hands on the game, but for now it appears that many do not appear to be too happy with the announcement.
