The worst of us ruin it for everyone else. It's just like how everyone reasonable hates microtransactions in gaming, but enough unreasonable people love them that microtransactions are still more profitable than traditional income streams so they're shoved into every game.
Reasonable people didn't want to pay for the deeply mediocre Hogwarts Legacy, but enough dumb motherfuckers ruined it for the rest of us by making it one of the most popular games the year it released.
Note: I only know it's deeply mediocre because I pirated it so I could critique how bad of a fucking game it is without putting money into JK Rowlings pockets. Seriously, I do no understand the love for that fucking game, it's narratively and gameplay-wise a pile of shit for real.
Pure nostalgia injected into the first parts of it from what I heard. It was many people's fantasy to travel to that world, from both casuals and terminally online people alike. Mediocrity doesn't matter when the presentation fully exploits deep personal connections people have with the material.
