The number of people with a World of Warcraft subscription has doubled since Classic was launched.
Speaking in an investor call – as reported by Seeking Alpha – Blizzard president J. Allen Brack claimed that the company knew that "it was important that players have a single existing subscription to support both games."
Having launched in August 2019, World of Warcraft Classic takes players back to the MMOs early days.
"We think about the WoW community as supporting both, even though Classic and Modern are very distinct experiences. And we're committed to continuing to support both of those experiences over the long term," said Brack.
"Given the content updates for Modern WoW, and the cadence that we have for Classic, we exited our year with a subscriber base that was double what it was at the end of Q2. And we also see players remaining engaged in both versions of the game.
"We launched Visions of N'zoth, which is a content patch for Modern WoW, in January. Engagement with Classic has been particularly strong in the East, and we see very high levels of player retention there."
In October 2019, the American firm revealed that World of Warcraft Classic had exceeded its expectations. Last November, Activision Blizzard COO Collister Johnson confirmed that Classic had contributed to an increased number of subscriptions.
