If you want that kind of barebones experience, I'd recommend moving up to raw AVR microcontrollers, like the ATTiny85, my favorite. They're a lot of fun, and they're bare metal entirely, no arduino board to baby you. Just 8K of ROM to put your compiled C into. You can get a row of around 10 of them for like $15, then you can fiddle with them however you like.
You could also consider getting into linux kernel driver development, knowledge which would be useful in both ARM and x86 spaces.
How much boot/init knowledge is required? I absolutely would like a touchscreen and either wifi or a modem with 4g capabilities/SMS.
Would it have enough CPU power to run a basic rougelike game written in C at 60fps? Things simple enough that the nes/snes can do with pixels instead of tiles which make those consoles life easier
Though, I'm starting to think you'd be better off writing such things as apps for Linux on the PinePhone. Wifi/4G support can be accessed easily that way, and you get full access to high-quality game frameworks like SDL2. Why reinvent the wheel, after all? You can write it in C, just like in microcontrollers/arduino. Many applications in Linux are.

However networking is outside of my realm unless I can access it through a library or AT commands.(07-30-2020, 10:35 AM)overdrawnfettuccine Wrote: How much boot/init knowledge is required?
