Immediately I have my doubts, considering PUBG is at the top of the list.
And 1.2 billion players? That can't possibly be right.
The world population may be almost 8 billion now, but still that would mean that almost 15% of the worlds population is regularly playing PUBG. That for a title that everyone I ever encounter say they played back in 2016-2017 when it was in Steam Greenlight, but since have have stopped playing.
Similarly, a BILLION people are regularly playing Crossfire? A tactical FPS game which I, a fan of tactical FPS games, have never heard of, and from the screenshots I cna find looks like a ****ty ripoff of Counter-Strike?
This just doesn't pass the smell test.
