Super Data Research has released their digital sales review of 2013, analyzing how much revenue was made from free-to-play, mobile, console, and PC digital content. In the free-to-play category, the top ten games based on revenues worldwide made a total of $3.574 billion. Yes, billion.
The top earner was CrossFire at $957 million, a free-to-play first-person shooter you've probably never heard of. League of Legends came in at second with $624 million, and Nexon's Dungeon Fighter Online came in at third with $426 million.
Other top earners include World of Tanks at $372 million, World of Warcraft with $213 million, Star Wars: The Old Republic with $139 million, and Team Fortress 2 at $139 million. Most impressive to me is that Lineage I, a game that's been out for 14 years now, made another $257 million last year.
Impressive, if not a little disheartening. There's additional stats worth checking out on Super Data Research, just brace yourself at the mobile section when you see how much Candy Crush Saga makes every single day.
