Hi there,
I have an idea for a mod, for which it would be quite nice to have friendly NPCs to converse with.
Looking at the wiki, I found a special called StartConversation, but the documentation is minimal, and source code comments imply the feature is unfinished.

Is this an abandoned feature, or is there something I've missed? If so, is there some other way to achieve dialogue in this engine?

"Abandoned" is going to be a matter of perspective I think. The feature exists currently to implement the quiz in Super 3D Noah's Ark. It uses the same script format as is used for Strife dialogs in ZDoom (USDF) with a few small extensions. It however is only implemented for the purpose of enabling the S3DNA quiz so it's not complete and probably not super useful. At this time there's so much that would be a higher priority that you could probably consider it abandoned. It's not deprecated or anything like that though.
