A playable WoW clone for ~$200 and two days: nine classes, a dungeon, and a 502
The creator shipped a vanilla-WoW-flavoured browser MMO built almost entirely by Fable 5: nine classes, three zones, a 5-player instanced dungeon. The most surprising part, he says, was how much it added that he never asked for.
Built on the side in two days and 91% of a Max plan (~$200), the game came with quest logs, threat metrics and spirit-release-on-death that the creator never specified. Then HN hugged it to a 502.
The skeptics' line: easy to mass-generate quests and classes, but movement, pacing and balance are exactly the parts a model can't shortcut, and they show.
A micro-MMO that shipped more than it was asked to
The Show HN points to World of ClaudeCraft, a browser MMORPG the creator says he vibe-coded with Fable 5. The repo is MIT-licensed. The pitch, from the creator himself in the thread, is dense: "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."
What struck him wasn't that it worked. It was the scope creep in his favor:
"the most mind-blowing part for me was how much it shipped that I never asked for… quest logs, threat metrics in the combat log, eating/drinking, spirit release on death." — the project's creator
The cost, counted: two days, ~$200, mostly recall
A reader did the accounting from the creator's Reddit notes and landed on the part worth pausing over:
"This was made in 2 days and 91% of the Max 20x plan… so roughly ~$200… I can't entirely wrap my head around the fact that I live in a world where a machine can create this with minimal intervention by humans… to the point where I'm willing to spend 10 minutes playing it." — a commenter who tallied the cost and tokens
The same commenter named the limit cleanly: a barrage of quests, gear and starter classes are easy to mass-generate, but movement feel, pacing and balance are the parts that need human iteration, and "the game itself is barely playable" without it. A skeptic put it shorter:
"It's impressive that Fable 5 was able to resynthesise something like this from its training data, but I am really not looking forward to more of this. What's the point?" — a commenter unimpressed by the resynthesis
Then the internet did what it does
The live demo didn't survive the front page. The thread filled with 502s and "hugged to death" — including from swyx, who pasted the raw nginx error. It's a fitting footnote: the model can stand up nine classes and an instanced dungeon in a weekend, but the single VPS behind it folded under an HN crowd. Impressive scope, real ceiling, and a server that proved the demo was the easy part.

From 'don't be evil' to 'don't be a pussy': an essay on how tech founders lost the room
The essay argues tech spent forty years building a specific kind of trust on boring motives, then liquidated it for attention. The thread mostly disagreed about why — and one reader said the title itself is the bait.
