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".
Virtual economy
The release of Blizzard Entertainment's World of Warcraft in 2004 and its subsequent huge success across the globe has forced both MMORPGs and their secondary markets into mainstream consciousness, and many new market places have opened up during this time. A search for WoW Gold on Google will show a multitude of sites (more than 90 sponsored results ) from which Gold can be purchased. Real money commerce in a virtual market has grown to become a multibillion-dollar industry. In 2001, EverQuest players Brock Pierce and Alan Debonneville founded "Internet Gaming Entertainment Ltd (IGE)", a company that offered not only the virtual commodities in exchange for real money but also provided professional customer service. "IGE" had a trained staff that would handle financial issues, customer inquiries and technical support to ensure that gamers are satisfied with each real money purchase. It also took advantage of the global reach of synthetic worlds by setting up a shop in Hong Kong where a small army of technically savvy but low wage workers could field orders, load up avatars, retrieve store goods and deliver them wherever necessary. This lucrative market has opened a whole new type of economy where the border between the real and the virtual is obscure.
