> many successful games come to iOS because it is a controlled environment, with negligible piracy. How does that make sense when all of those games were originally developed for the PC platform, which has rampant piracy, even above that of Android?
Every PC game developer sweats piracy. Windows is targeted first (or only) because it is the vastly dominant gaming platform. But the piracy aspect is real, and important, and it hurts Windows gaming. If you are developing a Nintendo Switch game, you can focus on building a better game, instead of anti-piracy techniques, or futzing with hardware incompatibilities. That's iOS too.
Or you could simply focus on the legit PC market instead of worrying about people who will likely never be your customers.
