2 years ago when i was student, in my class (30 boys, IT class) almost everyone was playing cs:go, during school we were just talking about game, memes, funny videos, tournaments, updates, etc. There were 20~ppl always online at the evening, playing cs:go. We had even school tournament, every class participated. Now when we're all done with school almost nobody plays csgo - there is just me and my friend. It was just super hyped game, but it is not anymore. Now the majority of cs:go players are people who liked that game during the hype, they're a bit skilled, so this is reason why they're still playing it. This game is only about getting better doing the same thing over and over again - same maps, same weapons, same everything except people. It might be boring for some people, and that's normal I guess.
Now this overhyped game is PUBG, I can tell people will be bored of it in 1-2 years.
@topic Game is far from dying ofc. It is still the most competetive fps game.
