Why it matters
World of Warcraft: Forever represents Blizzard's new direction for the long-running MMO, described by Bloomberg as a fundamental rethinking of the game. The unprecedented server allocation signals how seriously the company treated launch stability after past expansion debuts suffered from queue times and crashes. The scale of resources, over 250 terabytes of RAM, reflects both the technical demands of a 2026 MMO launch and Blizzard's determination to avoid the server issues that have historically plagued major WoW releases.
