Think of it a different way, you like city builder games, but you don't want to play one right now. You can buy 3 different city builder games for $10 during a sale. And when you do fancy a city builder, pick the one that most appeals in the moment.

By purchasing a bunch of different game cheaply, yoh have the choice of what kind of story/mechanic to play when you do want to play a new game.

You're speculating on your future desires, and you might as well get a selection when it's cheap.

A game pass subscription sort of scratches the same itch, but you don't own the games. So can't replay a few years later if you aren't presently subscribed.

It's not about being stupid with your money, it's actually a cheap way to give yourself choice in the future.
