Reclamation
In standard Minecraft, the world remains static - from the first spawn in the forest to the thousandth day after defeating the Ender Dragon.
Reclamation uses a datapack-configurable library that causes blocks near players to gradually transform and change over time. This adds more dynamics and life to the game world.
Flexible configuration through game rules and decay parameters allows for various effects: from a world rapidly crumbling under the weight of time, to a nightmarish gray goo infection spreading beneath your feet, or a practical building tool capable of creating more complex visual patterns than simple random noise.
