Multiplayer games as a whole don't last forever
Something better eventually comes along and the old ones die and people's preferences change over time.
The end game for everyone will be narrative focused single-player games. When you're a kid, you start by playing whatever you get your hands on, what your parents buy you, free online games, cool stuff that pulls you in to the world of video gaming, when you're adolescent and a teenager, you play the zoomzoom hyperactive multiplayer PvP garbage, then you grow out of them to appreciate slower paced games that tell a story, that can be played to a conclusion leaving a lasting impression.

I used to play PvP shit between the ages of 15-25, took them way seriously and played against the top brass, and holy fuck it was the most miserable time ever. They start out cool when it's all new, then you start to optimize playing them, and it becomes a mindless K/D / ranked grind. I wasted thousands of hours on those games and I have no fond memories about any of it. None of the kill streaks or ranked wins stay with you as it's all overwritten by the eventual loss and death streaks.
