Blizzard Entertainment announced that World of Warcraft will receive an official classic-style “vanilla” server. The news comes from the opening ceremony of this year’s BlizzCon event.

World of Warcraft Classic is Blizzard’s response to fans who have long begged for a server based on the original version of World of Warcraft.

“We want to reproduce the game experience that we all enjoyed from the original, classic WOW,” said executive producer J. Allen Brack, following a trailer that revealed the server.

Fans have worked on making their own vanilla servers over the years, some of which Blizzard Entertainment has shut down over copyright and other issues. But that hasn’t stopped players from wanting to return to the classic World of Warcraft experience. That typically refers to gameplay from prior to the Burning Crusade expansion, which dramatically changed the game when it launched in 2007. 2010’s Cataclysm expansion further removed content from what fans call the “vanilla” version of the game.

The official Classic version is currently in development, Brack said.
