I remember having an iPhone 5 and the quality of games were pretty good, albeit pricey. I did pay for a bunch of games at the time because I thought that was fair. Coming back to iOS a decade later and the quality of games is unrecognizable from the era I started in. Even Apple Arcade has a lot of stuff that feels like f2p/p2w stuff that is basically mobile casinos.
I tried to give a bunch of modern games a shot and they're essentially slot machines that gate game progress with pulls. I'm glad console and PC gaming hasn't been completely taken over by this, but it is very close.
