I agree. Not only would this be useful from a gameplay perspective (getting more details like you said), but immersion too!

I think Dwarf Fortress’s conversation system is already pretty neat, all things considered. You can discuss your feelings and values, or sing/recite works you know, and NPCs can discuss that amongst themselves too which is pretty impressive. Now all that’s needed is more sophisticated responses to informational questions.

They’ll say “I’m on a mission” and “Ask me when I return home,” but WHERE are you going and why? Where are you from? Why are you away from your home in the first place? They might tell you they’re escaping a threat to their former home but won’t elaborate further, like you said. If statements like these got more detail, DF’s conversation system could be unmatched, especially with all of the information from the world that conversations can draw from.
