Let the game choose a seed. Then remember it.

A blank world name or seed is a small menu decision with a lasting consequence. The prototype can resolve those choices for the player. Once it does, the chosen values need to belong to the save, rather than being generated again the next time that world opens.

The world-defaults development checks followed that path through creation and continuation. They recorded the resolved name and seed, generated nearby world chunks and checked the player’s spawn and collision. Loading the save then had to restore the existing world instead of quietly starting another one.

This is the kind of work that rarely makes a dramatic screenshot. It matters when Continue means what the player expects. The prototype checks also covered backup recovery and preserving existing saves. Choosing a world for someone is convenient; remembering that choice is what makes the convenience trustworthy.
