Just Gaming in general made something like $200 BILLION in revenue in 2025. Movies made ... $33B globally.
And of that $200B, mobile games were over half.
If the average HN'er would just think of the money they spend on their hobbies (or don't it usually doesn't end well =P) and now apply that to mobile games. They're a hobby or a way to relax for millions and millions of people.
They pay for the "predatory IAPs" because they consider the $10 spent a good investment on the fun they're having in the game they play.
There's a specific group of people who just have the mindset of "never pay real money for anything in a game" - I'm one of them. But even I have to admit that I'm in the minority.
