While it is true that there are a ton of great games out there, the reality is that if you enjoy multiplayer, community matters A LOT.
There was an excellent game released recently called Chivalry 2. It was an extremely fun "realistic-ish" sword fighting game with huge servers and excellent implementation.
Last time I checked, nobody was playing. This is true for SO MANY interesting multiplayer games.
So I feel what this person is saying. Popular multiplayer games are not to my taste these days ( I miss Quake III ). And there isn't a huge community for a lot of the games I am interested in. So it goes.
Another thing is: A lot of these games are made for young people. So yes they do dumb dances and are cringe-y but you have to just get over that. I very normal and was really into zombies when I was 11, I'm sure I would be doing the Fortnite dances as well. Though I may have been contrarian and into PUBG...
