I’m not 100% sure exactly what happened, but my best guess is that it just got stale quickly. The twitch streamers and kids who hop from game to game played for a few weeks, then when they got bored it just started dropping off in popularity, eventually leading to the death spiral.

I know at least for myself I just didn’t enjoy the gameplay loop as much as I did Apex legends, so I just went back to what I was familiar with and sunk another couple thousand hours in.
