Why do people torture themselves over a video game?

Look, I totally understand people wanting mechanics changed or balance adjusted or what have you. That's great. It's feedback that devs will hopefully use to improve the game.

There's an attitude I'm encountering more and more often, both in game, and on the forums of people saying things like, "this game is stupid for XYZ reasons. Why should I even resub?"

I don't understand this at all. If you're not having fun, don't resub. Go play something else or do something else. If the game comes back in a way that gives you joy, come back to it.

Hot take, but aside from some of the players I've run keys with, for the most part, I'm enjoying this season of M+. I'm also enjoying the raid and the delves and the open world stuff. I'm having a blast right now.

Back in the early days of BFA, I wasn't having fun. After having played for many years, I quit basically until a month or so before Shadowlands dropped. For some months in SL when I wasn't having fun, I quit again.

Why do people play a game they seem to despise? There are so many other games to play.
