I don't play many FPS games full stop. The ones I did play added a bunch of elements I didn't like (Destiny, Overwatch, etc). Since they don't make up the predominant portion of games I play, I can't say it's surprising to me.
Others have complained about the number of "mouth breathing kids" and I can't really fault them for that. The number of people in online games with no filters, who play loud music, or have family drama going on around them on hot mic is too high. The number of people who are rude or worse is also too high.
There's something, though, to be said for the kinds of games that are just more popular because they encourage a story and or exploration or both.
