A Small Steam Game Shows How LLMs Could Kill the Dialogue Tree

Verbal Verdict is the best use of generative AI I’ve seen.

Excerpts:

The Verbal Verdict demo drops me into an interrogation room with basic facts about the case to my left, and on the other side of a glass window are three suspects I can call one at a time for questioning. There are no prompts or briefings—I just have to start asking questions, either by typing them or speaking them into a microphone

The responses are mostly natural, and at times add just a bit more information for me to follow up on.

Mostly. Sometimes, the AI goes entirely off the rails and starts typing gibberish

There are, of course, still many limitations to this implementation of an LLM in a game. Kristelijn said that they are using a pretty “censored” model, and also adding their own restrictions, to make sure the LLM doesn’t say anything harmful. It also makes what should be a very small game much larger (the demo is more than 7GB), because it runs the model locally on your machine. Kristelijn said that running the model locally helps Savanna Developments with privacy concerns. If the LLM runs locally it doesn’t have to see or handle what players are typing. And it also is better for game preservation because if the game doesn’t need to connect to an online server it can keep running even if Savanna Developments shuts down.

it’s pretty hard to “write” different voices for them. They all kind of speak similarly. One character in the full version of the game, for example, speaks in short sentences to convey a certain attitude, but that doesn’t come close to the characterization you’d see in a game like L.A. Noire, where character dialogue is meticulously written to convey personality.

    Ooooh, I’d like that! Well, there’s 3 parts to the (random user input / scripted game output) conundrum:

    1. I think it is fair that if you ask, ‘Why didn’t you say something?’ the NPC might either respond as if it is being accused of sabotage, answer the damn question, lie, or prefer not to talk about it (it’s personal).
    2. I’d keep a short list of standard options – probably in a collapsed scroller kinda thing so you could either verbally say or type whatever you want, OR you could click an arrow to pick from a list. That way lazy or stuck players wou;dn’t have to think of all the options, and players interested in roleplaying could do as they please.
    3. I’m OK with, “I’m not going to respond to that”. I’d hope each character had several variations of that, but I think it is legitimate for NPCs to dislike being pestered. Shopkeepers might have replies like, “Are you gonna buy something or are you just here to bend my ear?” or “I don’t see how that relates to my inventory.” Random townies might reply, “Do I even know you?” or “Would you PLEASE stop bothering me.” or “You’re harshing my mellow, man. Shhhh… Just chill.”
