People quitting CS:GO

Basically; No new content, Same old gameplay routine.

But if you look at it from a diffrent perspective:
People just found new games that they enjoy more.

There is so much going on with releases right now that almost every "old" game gets hits in playercounts.

It's just like PUBG or League. It was all fun and entertaining untill theres new simillar games that get you that old feeling of exitment when playing it.
