Stellar Nomad: An open-source, browser-based space exploration game where players pilot a spaceship, mine resources, and venture through a procedurally generated universe.
Add ability to build one spacestation per orbit. Spacestations can then be entered to repair and upgrade the ship, store resources, and build more advanced technology. Should be necessary to build one pretty early in the game.
Would be fun if the players had a personal AI assistant, similar to GUPPI in the bobiverse books. Could either be there right from the start or would have to be build first.
Could be implemented with WebLLM: https://www.npmjs.com/package/@mlc-ai/web-llm
