Blizzard have never employed early access. Never. I wouldn’t even know it existed if the only thing I knew was Blizzard games.
That is completely alien to Blizzard, and even to most games on Steam. Only EA with BattleField 5 did it.
Which Blizzard? The one that made a Superman console game in the 1990s? Or the one who released zero products for 6 years straight (2004-10)?
