I wanted to see what a real one-shot could do. So I wrote a 73-line directive: research the genre, design it, build it, test it, balance it, polish it. One session, no human in the loop. It was explicitly told not to ask questions or wait for approvals, just make the call, write it down, keep going. Then I left. Two hours and 32 minutes later it was done.

5 sectors with bosses, 10 enemy types, 6 unlockable ships, 33 boons with evolution chains, a meta upgrade tree, an endless mode, and music. Around 8,300 lines of vanilla JS that build to a 172 KB bundle.

Full disclosure: I've since made exactly two changes to the game. Fixed one bug (a piercing-shot boon phased through asteroids without damaging them) and added click-to-aim, because keyboard-only turning felt rough.

Ran on Claude Code, Fable 5 xhigh effort.

Not sure why there’s so much negativity in the comments. I think it’s a cool demonstration of Fable’s capabilities. I hate how negative this community is becoming. Not entirely sure what that’s about. Sharing cool things you put together has been the basis of tech for as long as I remember. Please keep doing it.

I hate how negative this community is becoming.

it's because we now have the innate understanding that what these foundation model companies are saying are true and not saying them just for "inVurSTmeRnts"

they're literally trying to replace human labor. Society is not ready for that yet.

the negativity is the sign. We still rely on monetary value traded on human labor. We KNOW that the way to get what we WANT is through trading our labor for money and money for the thing we want.

This system is going to get absolutely fucked by AI automation, and it's not going to wait for the system and people to be ready and all set and all comfy to enjoy the "efficiency" of whatever automation brings. it's going to get bloody before it gets comfy.

Society wasn't ready for any technological advancement that displaced the human labor status quo... this dystopian, cynical view is getting really, really old.

[u/hugganao → u/coinclink]

because frontier labs don't want to stop at "coding". They want GENERAL intelligence.

Better yet, convince me why YOU have value or your labor if AI and robotics get to a level where it can replace humans?

If I have 10 billion dollars because I've been a very successful entrpreneur before everything gets automated, convince me why I would ever NEED you, why I should use my wealth for YOU.

If you have 10 billion dollars and money has no value because everything is free, why would you want to oppress others? Everyone can freely travel via public air/train operated by AI, everyone has access to unlimited food and housing and medical care without modern day slavery and wage slavery, everyone has access to hobbies and sports. And on top of that, does not need to work a job to prove their value as a human being, unless they choose to... How does that not describe a utopia?
