Tencent is working with its US subsidiary Riot Games to develop a mobile version of popular multiplayer online battle arena (MOBA) game “League of Legends,” Reuters reported, citing three sources with knowledge of the matter. According to Chinese game news outlet GameLook, Tencent and Riot Games had previously created demos for several prototypes. Despite the slow progress in the joint venture with Riot Games, Tencent did not leave the market open for competitors. “It will take a while for the mobile version of ‘League of Legends’ to be released in China, possibly not even in 2020. “League of Legends” was created by Riot Games in October 2009 and is the world’s most popular PC game in terms of number of monthly unique players.
