Creator here — fun to see this show up!
I built this with Fable over a couple of days, on the side. It's a vanilla-WoW-flavoured micro-MMO in the browser: nine classic classes, three zones, a 5-player instanced dungeon, parties/duels/trades, and persistent characters. Free to play: https://worldofclaudecraft.com — and fully open source (MIT):

Honestly the most mind-blowing part for me was how much it shipped that I never asked for. The level of polish and completeness coming out of the model genuinely surprised me — quest logs, threat metrics in the combat log, eating/drinking, spirit release on death.
We already have some contributors on GitHub!
You did a great job writing a prompt. Congratulations.
This is cool! I assume a lot of this was Fable orchestrating sub-agents with cheaper models, right? Something I noticed with Fable is that if it spun off three sub-agents in the cloud version of claude code, and then hit the 5-hour usage limit, all the work of those sub-agents would be lost (!). Did you run into the same thing?
One time though, I hit the limit when not running a sub-agent, and the agent resumed after the limit expired. Weird.
