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".
Heroes of the Storm
Heroes of the Storm is a multiplayer online battle arena video game developed and published by Blizzard Entertainment for Microsoft Windows and macOS, which released on June 2, 2015. The game features heroes from Blizzard's franchises including "Warcraft", "Diablo", "StarCraft", "The Lost Vikings", and "Overwatch". The game uses both free-to-play and freemium models and is supported by micropayments, which can be used to purchase heroes, visual alterations for the heroes in the game, and mounts. Blizzard does not call the game a "multiplayer online battle arena" or an "action real-time strategy" because they feel it is something different with a broader playstyle; they refer to it as an online "hero brawler". At the end of 2018, Blizzard announced that game was being transitioned to a long-term support plan, with some staff members moved to other projects and its official tournament circuit cancelled.
