I said “minecraft world file” which stores the chunks the player explored and potentially modified. And I said “could” not “must”, it depends on if hits a certain creative threshold.

If the player decides to teleport around while creating a dickbud or whatever by just the explored chunks, that could meet it.

If someone selectivly openes quests to use the open quest markers on a map in an RPG to create a dickbud, that cloud meet it as well.

The save game could tell your individual story through the game, that cloud meet the threshold as well.
