It hasn't taken as long as I thought, but PlayerUnknown's Battlegrounds has officially hit a huge peak of 2 million concurrent players on Steam.
At the time of writing, PUBG's new peak was 2,016,498 players while its closest competitor being Valve's Dota 2 with 622,839 peak players and Valve's other smash hit CS:GO with 568,207 peak players. Remember that this is Bluehole's first massive success with 15 million copies sold and $450 million in sales.
PUBG hasn't even hit consoles yet either, with an Xbox One version on the way and a possible release on the PS4 coming as well.
