Have people succeeded in having many conversation only sessions?
I think puzzles or talking to characters can be interesting and especially necessary to people who would have chosen colonist careers etc.
And i think it does alot for pacing and of course establishing characters.
I can make compelling characters but it takes me a long time to make characters i am happy with.
If people have any references or inspiration you like to use, or a link to a similar thread feel free to share. Or perhaps rules to how much NPC conversation you might include.
