Hey everyone! Petrus Lowei here 👋 - 3D AI creator behind Build0.city What inspired me to build this? I have to give huge credit to the dev who built Project0.city. When I saw what he created - a full city where 418 games were built by players with Claude Code and Codex - I was blown away. I thought: I need to build a tribute. So I built Build0.city - my own district on top of Project0. What problem am I solving? Building games today is lonely and hard. Unity/Unreal has a huge learning curve. And even with AI coding (Claude, Codex, Sonnet, GPT), you usually build alone in a vacuum. You ship to nowhere. I wanted a place where: Prompt = Instantly playable game IN a shared world where real players can walk in and play it. No engine. No export. No App Store. How my approach evolved: I started with just a blank lot. Then I connected my agent via MCP (using Higgsfield's MCP) and realized - wait, this can build LIVE. I prompted "build me a kart racer" and 3 minutes later people were racing on it. That's when it clicked. This isn't a game builder, it's a city builder. Your lot, your game, your economy. I would love for you to claim a lot and show me what YOU build. What will you prompt? Happy to answer any questions about MCP, Project0, or how I built it!
