When it comes to revenue, Riot Games often remains tight-lipped on the success of League of Legends. The game and its developer staff have grown considerably over these past few years — with LoL becoming the most-played game in the world — so it can be assumed that the game is at least earning a pretty penny. Thanks to SuperData, we now have a better idea as to how much.
According to SuperData's latest market update, League of Legends generated $624 million worldwide in 2013, making it second only to Crossfire, a South Korean free-to-play shooter which brought it $957 million during 2013. Interestingly enough, both games are published through Tencent, which actually owns a majority stage in League of Legends developer Riot Games.
Third on the list is Nexon's Dungeon Fighter Online with $426 million, followed by Wargaming's World of Tanks which generated $372 million. Rounding out the top five is another Nexon game, Maplestory, with $326 million. It appears EA's move to make Star Wars: The Old Republic free-to-play is paying off; the MMO finished 8th on the list with $139 million — tied with the amount generated by Valve's Team Fortress 2. World of Warcraft, a subscription-based MMORPG from Blizzard, also found itself on the list thanks to $213 million in sales generated through microtransactions.
Overall, the digital games market in the United States (including social, mobile, DLC, free-to-play, and subscription) grew by 11 percent, totaling $11.76 billion in sales during 2013.
