Warcraft
In 2004, Blizzard Entertainment moved the series away from the real-time strategy genre and released "World of Warcraft", a massively multiplayer online role-playing game (MMORPG). Requiring a subscription fee to be paid to play, it also introduced regular additional content to the series in the form of patches. "World of Warcraft" gained popularity worldwide, becoming the world's largest subscription-based MMORPG in 2008. The game reached a peak 12 million subscribers worldwide in October 2010. "World of Warcraft" has had seven expansions as of 2018. During the production of "", Blizzard co-founder Frank Pearce stated that "If there's a team that's passionate about doing another "Warcraft" [real-time strategy], then that's definitely something we would consider. It's nothing that we're working on right now, we have development teams working on "", "", "Diablo III", and when those teams are all off the projects they're working on, they'll be intimately involved in the discussions about what's next".
Collectible card game
The previous years influx of new CCGs continued into 2006. Riding on the success of the popular PC Game "World of Warcraft", Blizzard Entertainment licensed Upper Deck to publish a TCG based on the game. The "World of Warcraft" TCG was born and was carried by major retailers but saw limited success until it was discontinued in 2013 prior to the release of Blizzard's digital card game "Hearthstone". Following previous trends, Japanese-influenced CCGs continued to enter the market. These games were either based on cartoons or manga and included: "Naruto", "", "Bleach", "Rangers Strike" and the classic series "Robotech". "Dragon Ball GT" was rebooted once again in 2008 and renamed as "Dragon Ball".
