24 alternatives to World Engine – Build Worlds Like Brandon Sanderson
Hey HN, After hours of re-watching Brandon’s creative writing BYU lectures[1], we converted his ideas into a framework to rapidly iterate and build sci-fi fantasy worlds. The app is divided into 3 sections: - World: To create a unique magic system intertwined with distinct physical and cultural phenomena - Characters: To create character arcs and give them unique traits that evolve over time - Plot: To weave a series of events in this world following the character arc We are newbie devs, any suggestions on the app improvements and usability would be great! The idea is to capture the essence…

Magic Patterns▲566I built an agent that helps you build Rollercoaster Tycoon-influenced theme parks. You can prompt something like “Build me a cool theme park” and it’ll build a cohesive theme park with multiple worlds and connected with paths and rides. The weird part is that I built it using the same ideas we use to make AI-generated websites follow a company’s design system. I work as an engineer at Magic Patterns, focused on building our Design System Agent, aimed to use your existing brand, components, and conventions instead of producing something that looks like generic AI-generated UI. By default,…

In the wake of all the Unity nonsense, just wanted to toss the Raverie engine into this mix :) We’re building off a previous engine that we worked on for DigiPen Institute of Technology called the Zero Engine with a similar component based design architecture to Unity. Our engine had a unique feature called Spaces: separate worlds/levels that you can instantiate and run at the same time, which became super useful for creating UI overlays using only game objects, running multiple simulations, etc. The lighting and rendering engine is scriptable, and the default deferred rendering…

Hi HN, I'm Kai Wang, one of the creators of Yuanzai World. We built a simulation engine (currently on iOS & Android) that allows the community to create and share text adventures populated by multiple LLM-based agents. Unlike standard chatbots, our focus is on community co-creation—users define the worldviews, and our agents (with persistent memory and social relationships) bring them to life. The cool part: We implemented a system we call "World-Line Divergence" (inspired by visual novels like Steins;Gate). Usually, AI RPGs feel random or infinite loop. We built a state machine that tracks…

Modd.io is a collaborative game editor that runs in browser. It's kind of like Figma for game dev. We made this engine low-code and multiplayer-first, so developeres can quickly prototype casual multiplayer games. I hope some of you guys will find this useful. Would love to hear feedback also. Thank you. Engine Demo: https://www.modd.io

It's a web app that uses AI to turn any book into a playable text adventure. Your favorite book, but your choices, hence your story. You can even "remix" the genre like playing Dune as a noir detective story. Note: Work in progress. Suggestions are welcome.

Took a break from the falling sand simulation blog posts this week to work on another small project. It's a little pixel world generator- each time you visit, you'll see a new little world. I really like this stuff and had a blast building it yesterday!

Hello, Hacker News! My name is Lillian (see: http://about.lillian.link/), and I just released version 0.2 of my MIT-licensed game engine, Hypatia(http://lillian-lemmer.github.io/hypatia/). Hypatia is a game engine for single player 2D action adventure games. You can use it to make a game like Legend of Zelda: Oracle of Ages and Oracle of Seasons. Hypatia is aimed at non-programmers and programmers alike. I'm seeking any sort of feedback. Hypatia supports FreeBSD first, but has great support for just about any platform…

Hi HN, we built world-model-optimizer, an open source tool to continually improve a specialized model for an agent. It does this by simulating production tool responses through text world modeling (similar to QwenAgentWorld, summary here https://x.com/silennai/status/2073887455884058814). We can then use this to train a router for frontier, OS, and local models (use defaults or pick which ones to optimize against). wmo ingests agent traces, builds the simulation, embeds the traces, runs different models you choose against the simulation scenarios, and then uses a KNN…

Hello HN, Just wanted to show this little 2D game engine that I've been working on for some time (around 2 years on the editor part, longer on some of the components). It's quite full featured but obviously this a project of such magnitude already that the work never really ends. That being said it's definitely already at a point where games can made and published. The editor runs natively on Windows and Linux using Qt5. The games can run on both Win and Linux as well as on WASM with WebGL. Feature wise there's a bunch of the stuff you'd expect. Audio, graphics, scripting,…
