Robotopia: A 3D, first-person, talking simulator (opens in new tab)

Our initial plan was to simply ask enough for the game that the price would cover the costs on average... but that means that we're basically encouraged to have people play the game as little as possible? We're looking into some kind of subscription now, it sounds weird but I do think it's a better incentive in this case. Plus we can actually ask for less upfront.

Thanks :) If you want I'm on the discord linked on our landing page, it's fun stuff to talk about!

Not the founder, but having run conversational agents at decent scale, I don't think the cost actually matters much early on.

It's almost always better to pay more for the smarter model, than to potentially give a worse player experience.

If they had 1M+ players there would certainly be room to optimize, but starting out you'd certainly spend more trying engineer the model switcher than you would save in token costs.

Thanks :) It may sound insane but we convert actions to Python functions then ask the LLM to write a python script that actually runs in IronPython inside the game. Then we have a visual Behavior Tree system to let our designer define the actions. So yeah, they got a bunch of general actions like walk, talk, follow, interact etc.

PS: I think MCP/Tool Calls are a boondoggle and LLMs yearn to just run code. It's crazy how much better this works than JSON schema etc.

Yes, but every language is going to be a "port", not something contracted out like traditional localization. I haven't decided how exactly but language conversion will land somewhere between these two extremes: 1. (expensive) pick a suite of "native" models (eg. models from China), TTS, ASR. Rewrite all the prompts in the target language. Revalidate all characters by hand 2. (cheap) slap a translation model around input and output and let the game run in English internally. My gut feeling is that this could have very poor results though and increase latency.

It's definitely a research project, this has never been done before.

The "big" one is Llama3.3-70b on the cloud, right now. On GroqCloud in fact, but we have a cloud router that gives us several backups if Groq abandoned us.

We use a ton of smaller models (embeddings, vibe checks, TTS, ASR, etc) and if we had enough scale we'll try to run those locally for users that have big enough GPUs.

(You mean the voxel grid visibility from 2014?! I'm sure I did at the time... but I left MC in 2020 so don't even remember my own algorithm right now)

Hah from my knowledge of traditional AAA, there is 0 chance any AAA in development right now uses LLMs. A lot of them don't even use it for coding and gamedevs' mood about AI is abysmal.

Why? Because they feel like it needs to be a part of the game?

What's interesting is you might not want to see de novo AI-generated storytelling (slop factor), but you might really like the way AI can make a story crafted by humans more interactive.

I would personally avoid voices that skew too close to common tiktok TTS ai. Currently the heavy robots with the lower bassier voices sell that clunky robot voice vibe much better, but some of the more generic voices immediately take me out.

Robotopia was very inspired by suck up. First LLM game that kinda cracked the 3d world
