next up: Crusader Kings III

Crusader Kings is a franchise I really could see LLMs shine. One of the current main criticisms on the game is that there's a lack of events, and that they often don't really feel relevant to your character.

An LLM could potentially make events far more aimed at your character, and could actually respond to things happening in the world far more than what the game currently does. It could really create some cool emerging gameplay.

Can't wait for someone to let Claude control a runescape character from scratch
I've done this! Given the right interface I was surprised at how well it did. Prompted it "You're controlling a character in Old School RuneScape, come up with a goal for yourself, and don't stop working on it until you've achieved it". It decided to fish for and cook 100 lobsters, and it did it pretty much flawlessly!

Biggest downside was it's inability to see (literally), getting lists of interact-able game objects, NPCs, etc was fine when it decided to do something that didn't require any real-time input. Sailing, or anything that required it to react to what's on screen was pretty much impossible without more tooling to manage the reacting part for it (e.g. tool to navigate automatically to some location).

Would a way to take screenshots help? It seems to work for browser testing.
> We don't know any C++ at all, and we vibe-coded the entire project over a few weeks. The core pieces of the build are…

what a world!

First time I am seeing realistic timelines from a vibe-coded project. Usually everyone who vibe codes just says they did in few hours, no matter the project.
The opening paragraph I thought was the agent prompt haha

> The park rating is climbing. Your flagship coaster is printing money. Guests are happy, for now. But you know what's coming: the inevitable cascade of breakdowns, the trash piling up by the exits, the queue times spiraling out of control.

Edit: HN's auto-resubmit in action, ignore.
> The only other notable setback was an accidental use of the word "revert" which Codex took literally, and ran git revert on a file where 1-2 hours of progress had been accumulating.

If I tell Claude to "revert that last change, it isn't right, try this instead" and Claude hasn't committed recently it will happily `git checkout ...` and blow away all recent changes instead of reverting the "last change".

(Which, it's not wrong or anything -- I did say "revert that change" -- it's just annoying. And telling `CLAUDE.md` to commit more often doesn't work consistently, because Claude is a dummy sometimes).

Interesting article but it doesn’t actually discuss how well it performs at playing the game. There is in fact a 1.5 hour YouTube video but it woulda been nice for a bit of an outcome postmortem. It’s like “here’s the methods and set up section of a research paper but for the conclusion you need to watch this movie and make your own judgements!”
> kept the context above the ~60% remaining level where coding models perform at their absolute best

Maybe this is obvious to Claude users but how do you know your remaining context level? There is UI for this?

This is a cool idea. I wanted to do something like this by adding a Lua API to OpenRCT2 that allows you to manipulate and inspect the game world. Then, you could either provide an LLM agent the ability to write and run scripts in the game, or program a more classic AI using the Lua API. This AI would probably perform much better than an LLM - but an interesting experiment nonetheless to see how a language model can fare in a task it was not trained to do.
Wonder how it would do with Myst.
I love the interview at the end of the video. The kubectl-inspired CLI, and the feedback for improvements from Claude, as well as the alerts/segmentation feedback.

You could take those, make the tools better, and repeat the experience, and I'd love to see how much better the run would go.

I keep thinking about that when it comes to things like this - the Pokemon thing as well. The quality of the tooling around the AI is only going to become more and more impactful as time goes on. The more you can deterministically figure out on behalf of the AI to provide it with accurate ways of seeing and doing things, the better.

Ditto for humans, of course, that's the great thing about optimizing for AI. It's really just "if a human was using this, what would they need"? Think about it: The whole thing with the paths not being properly connected, a human would have to sit down and really think about it, draw/sketch the layout to visualize and understand what coordinates to do things in. And if you couldn't do that, you too would probably struggle for a while. But if the tool provided you with enough context to understand that a path wasn't connected properly and why, you'd be fine.

I see this sentiment of using AI to improve itself a lot but it never seems to work well in practice. At best you end up with a very verbose context that covers all the random edge cases encountered during tasks.

For this to work the way people expect you’d need to somehow feed this info back into fine tuning rather than just appending to context. Otherwise the model never actually “learns”, you’re just applying heavy handed fudge factors to existing weights through context.

this is cute but i imagined prompting the ai for a loop-di-loop roller coaster. If this could build complex ride it would be a game changer.
Interesting this is on the ramp.com domain? I'm surprised in this tech market they can pay devs to hack on Rollercoaster Tycoon. Maybe there's some crossover I'm missing but seems like a sweet gig honestly.
yeah really - ramp.com is a credit card/expense platform that surely loses money right now...

pretty heavy/slow javascript but pretty functional nonetheless...

Why would they be losing money? It’s what we use for tracking expenses and getting comped for travel, meals, software licenses etc - works great in my experience. I can click a few buttons and get a new business expense card spun up in less than a minute, use it to make a purchase, get approval and have the funds transferred. Boom easy.

Do you not think they’re charging enough or something?

This was an interesting application of AI, but I don't really think this is what LLMs excel at. Correct me if I'm wrong.

It was interesting that the poster vibe-coded (I'm assuming) the CTL from scratch; Claude was probably pretty good at doing that, and that task could likely have been completed in an afternoon.

Pairing the CTL with the CLI makes sense, as that's the only way to gain feedback from the game. Claude can't easily do spatial recognition (yet).

A project like this would entirely depend on the game being open source. I've seen some very impressive applications of AI online with closed-source games and entire algorithms dedicated to visual reasoning.

I'm still trying to figure out how this guy: https://www.youtube.com/watch?v=Doec5gxhT_U

Was able to have AI learn to play Mario Kart nearly perfectly. I find his work to be very impressive.

I guess because RCT2 is more data-driven than visually challenging, this solution works well, but having an LLM try to play a racing game sounds like it would be disastrous.

> "Where Claude excels:"

Am I reading a Claude generated summary here?

Yes I believe so. Also things like forcing a "key insight" summary after the excels vs struggles section.

I would take any descriptions like "comprehensive", "sophisticated" etc with a massive grain of salt. But the nuts and bolts of how it was done should be accurate.

"i vibe coded a thing to play video games for me"

i enjoy playing video games my own self. separately, i enjoy writing code for video games. i don't need ai for either of these things.

That’s not the point of this. This was an exercise to measure the strengths and weaknesses of current LLMs in operating a company and managing operations, and the video game was just the simulation engine.
Claude Code in dwarf fortress would be wild
Given dwarf fortress has an ASCII interface it may actually be a lot easier to set up claude to work with it. Also, a lot of the challenges of dwarf fortress is just knowing all the different mechanics and how they work which is something claude should be good at.
I corroborate that spatial reasoning is a challenge still. In this case, it's the complexity of the game world, but anyone who has used Codex/Claude with complex UIs in CSS or a native UI library will recognize the shortcomings fairly quickly.
Most interesting phrase: "Keeping all four agents busy took a lot of mental bandwidth."
> As a mirror to real-world agent design: the limiting factor for general-purpose agents is the legibility of their environments, and the strength of their interfaces. For this reason, we prefer to think of agents as automating diligence, rather than intelligence, for operational challenges.
