The thing that gets me about Dwarf Fortress is that it's a 64-bit text-mode game.

As a grey-haired developer who got excited about "DOS Extenders" that allowed 32-bit mode, seeing a text-mode game written as a native 64-bit application is bizarrely anachronistic.

I get a similar feeling from text-mode GUI frameworks for Rust, which allow multi-threading and 64-bit but are essentially clones of Borland Turbo Vision, where you had to be mindful to keep lists smaller than 64KB: https://github.com/gyscos/cursive
