This is just one example that proves that Fable is in a dramatically different league than Opus, 5.5, etc.
Try doing this with Opus. It's nearly impossible. You could spend hundreds of hours and not get close.
Fable did this by looping over several prompts over two days.

While we wait for Claude Fable 5 to come back, here's another wild demo I built for Alpha School.
A 3D game that generates itself on the fly, fusing what a kid has to learn with what they're actually into.
Just the first prototype, done in two days with Fable.
(sound on!)
