You should not install a game requiring kernel level privileges on a personal machine you use for anything other than gaming.

At this point, I recommend to go the console way (or dedicated gaming machine, which is basically the same at this point as you are not owning neither of them)

Hahah apple does so since iOS 1

iOS is designed from the ground so that people are trained to think in apps rather than files

This is why it took so long until files appeared and why it is still no file browser like in any other operating system (only local directories for some apps and cloud folders)
