I haven’t seen it mentioned here, so just an FIY: Linux Mint is a “regular” distro, while Bazzite is an immutable distro, meaning the root filesystem is read-only.
That means a lot of the “normal” ways of doing stuff you find online will need to be done differently. For example installing system level packages requires a reboot, to boot in to the new “system image”. If something gets booked you can reboot in to an old system image to recover. Regular desktop (Flatpak) apps can be installed without rebooting.
Bazzite is based on Fedora, and very similar to Fedora SilverBlue (immutable version). So if you can’t find answers when looking online “how to do X in Bazzite” try instead “how to do X in SilverBlue”.
And FYI Linux Mint comes with an easy to use app Timeshift for system level backup and restore (by default it does not backup your documents etc in your HOME folder). Very handy to recover from a borked update or installing something you shouldn’t have.
I’d argue Skyrim etc have an “open world” above ground in addition to many “linear worlds” , i.e. the caves and houses behind loading screens. Open world games let you choose where to go and how to get there, as opposed to linear “corridor” games like Half Life or Halo where you literally follow a single path from A to B as you progress from one level to the next.
Then there’s games like original Fable which blurs the line, because technically you choose where to go and how to get there, but each loading area is so small, it doesn’t feel like an open world at all. And also you can’t go off the path.
Btw if you don’t like loading screens, have you tried Space Engineers? You can literally travel from one full sized planet (~40km diameter) to another full sized without a single loading screen. While flying you can walk around the inside or outside of your spaceship, no loading screens.
