What do you recommend to them if they do want to game?

If you count Android too, then this: I got my first Android phone when I was 10 or 11 and rooted it on the first day of having it. This was during a time when we were all still using ClockworkMod because TWRP didn’t exist yet, and I somehow ended up with a system without a kernel. Panic ensued, and I spent that entire night (like 10 hours) digging through xda in order to find a tutorial on how to get this damn phone to run again. Imagine having to tell your parents “I broke my phone I got yesterday.” I did get it working at like 6:30 AM. Fun times.

You probably have to explain what Serial actually is.

Unfortunately not possible for me. I daily Arch (btw) and hadn’t booted into Windows for months and months until my university professor came along and said “btw, we’re gonna build GUIs using Microsoft Foundation Classes in Visual Studio now, and yes, you have to use Visual Studio on Windows in the exam”. So nope, not uninstalling Windows.
