World of Warcraft: Classic is an adaptation of the original World of Warcraft for modern server hardware, announced by Blizzard Entertainment at BlizzCon 2017 on November 4, 2017.

The announcement comes in the wake of private server Elysium briefly imploding in October 2017 due to a staff member embezzling funds, and another selling characters and gold for real currency to players. In April 2016, a cease-and-desist letter was sent to another private server, Nostalrius.
