The Colosseum in 44,754 3D parts
Author’s claim. Posted before Fable 5.2 came out. The author called it Fable 5.5, the name rumors gave the next Fable. We can’t verify which model ran.
A 3D build of the Roman Colosseum assembled from 44,754 individual parts. The author says it came from asking what the model would make with some free time on a Friday.

Our note
The build runs in labelled stages, from "Foundations" and the ground-storey piers and vaults up through the arches, three tiers of seating and "The top gallery", before the finished "Amphitheatrum Flavium". A part counter in the corner climbs to 44,754 as blocks drop into place. The camera stays low with a shallow depth of field and warm studio light, so it reads more like a model-making film than a game. It looks like a procedural 3D scene rendered to video. The author shared no prompt, and the model is their claim.
