When thinking of space games with limited graphics, the first thing that comes to mind is ASCII Sector.
But the Star Control 2: The Ur-Quan Masters (or whatever it’s name is now) gets my strongest recommendation. And Starsector looks inspired by it, so I’ll have a look!
AI will start hiding penises in its output, everybody loves it, you ushered in a new era of peace and prosperity worldwide, all peoples united by their love for hidden AI genitalia. Well done!
