Check out the System Shock remake if you have a gaming PC. I recommend Dying Light as well; the parkour traversal and zombie physics are unmatched.
'Return of the Obra Dinn' is another favorite of mine.
Games that hold your hand and provide waypoints to every objective (i.e. built-in walkthrough syndrome) strip the joy for me personally.
How did you manage to launch CMD from the Ally? Is it possible using the built-in touch keyboard during setup? I don't have a USB-C keyboard to connect, unfortunately.
EDIT: I found a workaround: if you enter nonsense during the Microsoft sign-in it will fail and prompt to create a local account.
