Tencent made a nearly $400 million investment to control Riot Games back in 2011 and it has been reaping the rewards ever since. Riot Games is the developer of the popular free to play MOBA, League Of Legends. League Of Legends has since become the top grossing PC game for two years in a row (dating back to 2014) and made $1.7 billion last year (excluding December’s revenue).
There is a reason to believe that for the year of 2016 League Of Legends revenue was about $1.9 – $2.0 billion due to Christmas and the holidays where many players receive gifts such as Riot Points as well as Christmas bonuses at their respective workplaces.
With the recent introduction of Mystery Box’s in the game, players are likely to spend more money trying to gamble on the off chance of receiving rare and premium items from said boxes. This model is very common in many MMO’s with micro transactions such as Aion, Star Wars The Old Republic, and much more.
SuperData Research estimates that the F2P (free-to-play) PC games’ revenue will hit $21.3 billion by the year 2019. Similar estimates pin the range as high as $25 billion due to the rising popularity of e-sports and the introduction of micro-transactions to accelerate player’s ranks and skills in games such as DOTA 2 and League Of Legends.
