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
