This is an old project of mine. I made it a few years ago, so it's pretty out of date, but I can tell you my experience with it:

When I was playing around with it, characters tended to be very one-dimensional. They all had a single personality trait, and the AI made sure you knew about it. The particular way I set up the dialog system, multiple AI characters could interact with each other, but that ended up to very long conversations which quickly got off track and everyone forgot the original goal (which is a little bit too realistic) The AIs also found clever ways of speaking for other characters.

As for an AI DM, it just wasn't there yet. It didn't have the initiative to actually switch from one scene to another, and wouldn't create any NPCs to talk to. I often had to manually edit what the DM had printed so the session could move forward.

It was an interesting project, and my friends seemed to love it, but I think their love is mostly due to the custom characters I made for it.
