Everyone knows that Dota 2 is by far the most played thing on Steam, but it still keeps breaking records. This weekend, over one million gamers were playing Dota 2 at the same time. The number of concurrent users on Steam peaks at around 8.5 million, which means that Steam owes a huge chunk of its player base to Dota 2.
In second place, and far, far behind in player numbers, is Counter-Strike: Global Offensive, with around 433,000 peak concurrent players. This current influx of Dota 2 players is caused by the New Bloom update that premiered last week.
Still, Dota 2 has a long way to go to compete with League of Legends. According to Riot Games, LoL's concurrent players record stands at 7.5 million, with 27 million players logging in daily.
