Ooooh ok.
So, maybe this is a bit of a stretch...
But would the modern, open source, Fallout Online, which basically takes FO1/2, rebuilds them libre from the ground up, and makes them multiplayer... would that maybr be closer to a MUD, like a 'Graphical' MUD, with sprites instead of ASCII?
I've not actually ever played DF, but I have seen that nowadays, there are... basically ways you can translate all the ASCII into sprites or tilesets.

I get that the MU is multi user, I've just also never actually played DF, did not realize it had not network able capacity, derp.
Or you could maybe even say that with like, PokeMMO, which roughly smashes all the GBA era pokemon games into a massive online framework... thats a sort of 'graphical' MUD?
Yeah as I said, I'm too young to have ever played an actual MUD, thank you for clarifying!
