So what were the most popular PC Games of June 2014? Well not the most accurate statistics as not everyone uses Raptr, their monthly numbers do give us a good idea of what everyone around the world is playing. Topping the list is League of Legends with 16.76% of all PC Gamers, that is twice the percentage of the #2 game which is DOTA2 at 8.15%.
Following DOTA 2 is World of Warcraft with 6.13%, then Counter-Strike: GO with 3.20%. These statistics are close, but not exactly the same as Steam Statistics as Steam does not list many of the games listed here.
