A report from SuperData claims five MMOs are currently making over $100 million a year but that the MMO is declining year after year.
The single biggest MMO is Blizzard's World of Warcraft, this game has a marketshare of 36 percent and has an annual revenue of $1,014 million in 2013! The second place is taken by Lineage, a 16-year old MMO created by South Korean gaming firm NCSoft. Lineage has a marketshare of 9 percent and pulls in a yearly revenue of $253 million. NCSoft also has three other titles in the top 10: Aion at the seventh, Blade and Soul at the eight and Lineage 2 at the ninth place.
The third most popular MMO is TERA: Online, with a marketshare of 8 percent this game earns $236 million in revenue a year and the fourth spot is taken by EA's Star Wars: The Old Replublic, this game has 6 percent of the market and pulled in $165 million in 2013.
The top five is rounded out by Lord of the Rings Online with $104 million a year and the sixth place is occupied by EVE Online with $93 million. The top ten is completed by RIFT, this MMO has a marketshare of just 1 percent and takes home $36 million in revenue per year.
SuperData points out that the MMO market has been declining every year since 2010 with subscription numbers dropping from 30.6 million to 23.4 million. However, the research firm claims the loss in revenue from fewer subscribers has partially been mitigated by microtransactions and different payment methods.
