Android AOSP is a solid operating system for a console. There are already many existing games that will be playable, even if they were not designed for a grayscale console.
There will be a custom Launcher for a better user experience, but it will be possible to launch the console as a normal android OS for power users.

I have chosen Android AOSP for the operating system on an ARM64 chip to maximize the compatibility with popular game engines.

This  will allow game developer to easily port or create original games for the PageBoy.
