Finally Open-sourcing it today before Fable 5.5 drops or I will be doomed. Processing img uadc80we8wwh1... I’ve been trying to open source my MMORPG for the past two months, but new AI models kept releasing. First, I built it with Fable, and it was GLORIOUS. I could run around the open world, hack monsters, take on quests. However, the graphics were meh. It had dungeons, but without roofs, and lots of floating walls. Essentially every character, monster, and world assets were public CC0 assets, and credits to KayKits and Quaternius as most of the CC0 assets came from them. Everything worked and I thought I was done... Then came Astra. Wow! It could 3D model using Blender! So off I spent the next few weeks remodeling whatever I could with Astra. Custom gear, weapons, new buildings, new trees, grass. I sent Astra to rebuild all the dungeons so that they had proper walls and roofs. I replaced the CC0 monsters and character models with Astra made ones. I kept running out of usage limit on my ChatGPT Pro 20x (when they had 20x) plan, and so I was purchasing limit rests every 3 days for a few weeks. Just when I thought I was for sure done, Opus 5.5 dropped. This model is a Blendering beast! So off again, remodelling the trees, rocks, grass, walls, all the buildings, and monsters. With Opus 5.5, I could launch a workflow and let multiple agents remodel in parallel the thousands of assets I now had, and still manage to make my usage last until the end of the week (I did use one free reset they gave out a few weeks ago though). Anyhow, I was super ambitious with this game, and it still has a ton of rough edges. I have a lot of nostalgia about FFXI, so I really based this game's play style around it. I hear Fable 5.5 is right around the corner, I need to stop now while I am ahead. Source code is here (MIT): https://github.com/philipqnguyen/vanai Feel free to clone, make PRs, whatever you want. There are instructions to self host. The game is here if you want to try it out https://www.vanaiworld.com/ Yes, Opus 5.5 made the trailer, audio, it even signed in as multiple players to capture battle scenes for the trailer. I limited the game to just run in Chrome because it is currently more performant on Chrome. Also, credit to World Of ClaudeCraft for being a trail blazer in the AI built MMORPG space. If you haven't seen them, check them out https://github.com/levy-street/world-of-claudecraft EDIT: Someone suggested screenshots... So here is what it originally looked like on Fable when I first started: Processing img ic7v1ebq7wwh1... Here is what it looks like now, character assets mostly from Astra, but monsters and environmental assets from Opus 5.5: Processing img zyrnh6nf8wwh1... Processing img gdqo9f109wwh1...
