Sadly because it works, mobile gaming is bigger money-wise than PC and consoles combined, all because people are susceptible to short term dopamine hit your can buy any time, it's a part of what we call enshittification, making the product less user friendly and make more money, shareholders are happy, your don't have to

Best mobile games are Nintendo DS games that are completely touch based, which end up feeling like native experiences such as Kirby Mass Attack.

Because everything sucks now.

They are out there but I struggle to find good ones.

Not gonna lie I'm still hitting clash of clans... Paid for maybe 5 months of gold pass but no longer been playing since I was in middle school. Took like 6 years off though

At least in Android you can install old games yet, I just installed Nimble Quest and had a blast as of recently.

The good ones are mostly pc ports (dead cells, stardew vally)

The only good new mobile games are on Apple Arcade, which is behind a paywall. It sucks but what can ya do.

Have they ever been good? The sad thing I can tell you as a mobile dev(not game though) is that people on Android don’t want to pay for apps or games, on iOS it’s a bit better but still way worse than PC or PlayStation. There’s also rampant piracy on Android, both from users but even more so from shady app clones Google ignores. As a result free to play, always online with microtransactions is basically the only way to make money
