I've been experimenting with Fable 5.1 and it's ability to one-shot from a reasonable PRD, and then follow up/evaluate its work and then create/improve via a ticket stack and loops. This is a Friday afternoon prototype and fun to play. Enjoy!

The AGI disaster mode is particularly fun. Start a city in 2050 and deploy.

Depends on the disaster!
