[2023] Why do people say they'll quit after Apocalypse?

I see a lot of people talking about getting Apocalypse unlocked and then quitting the game?

Why is this?

My theory is something like this: Imagine you were a part time, for fun only, mountaineer climbing Everest for the first time and you were 95% of the way there BUT near death. The exhaustion has really started to bite, you have hit the wall but you are determined to push on. Imagine if someone came by and said "Hey, bet you can't wait to climb Everest again next year, but it's gonna be twice as hard because it's actually gonna be Galactus" ...

you would look at your ravaged body and think seriously to yourself "I'm never doing this again , this isn't even fun anymore".
