#1 concurrent players this weekend for the first time, 930k. That means over 11 million copies sold. It's been growing by 40,000+ every weekend and no end in sight.
Meanwhile, DayZ all time peak was 45,000, and that was just after release. After that it was in decline instantly.
PUBG is the proof that gamers don't want to be underestimated by these consolized, Ubisoft hand-holding games. In fact, most of us have been desperate for something like PUBG for a long time. One decently made hardcore game (look what you could have been DayZ if you weren't developed by retards) instantly becomes insanely popular.
I hope developers take note, though realistically it's probably too late for the triple A studios with their producers and men-in-suits making the decisions. I don't even think PUBG is designed that smartly (it has way too many random elements, e.g., in recoil patterns, for me to really take seriously) but it's still a breath of fresh air.
