On the advice of Paulie420 I've installed Dwarf Fortress, which I would describe as a "Modern ASCII Game." It's a lot like Dungeon Keeper from the 90's which I simply loved back then. However the UI looks like the classic Unix simulation "Life".
It's delightlyfull technical, retro, and amusing all at once. It even has a decent musical soundtrack, which I was suprised by coming from an ASCII UI.
