Complete Chaos
Complete Chaos rewrites how the world behaves, so familiar blocks, mobs and crafting results change in unexpected ways once it is installed on Forge 1.20.1.
What it does
The mod changes the rules of Minecraft Java Edition for 1.20.1, targeting Forge. Its author describes it as turning the usual game upside down: interacting with the world produces random results, and the gameplay is shaped by more than 200 deliberate changes. Blocks, mobs and textures are added alongside the altered behavior, along with a small number of new villager trades and recipes.
Large explosions and randomly generated structures can appear in the world, and some items may be destroyed by the chaos. The author states that the changes were balanced so the game stays playable and beatable, and that important items remain obtainable. The mod is still being tuned, and the author asks players to report bugs on the latest version.
Complete Chaos is for Forge players who want a rebuilt experience in a world that keeps its existing progress. Servers and clients both need it, and the license is MIT License, which means the mod is not open source.

Use cases
Playing for surprise
A player who wants a familiar world to feel new can play through and relearn how things behave.
Watching others play
The changes are described as funny to watch, so the mod suits streams and shared sessions with friends.
Who it’s for: Players who want Minecraft to feel unpredictable, and groups who enjoy watching a chaotic run. Server owners who want randomized rules for a shared world can also install it.
How it compares
Minecraft Chaos Edition is a Forge mod for 1.20.1 that runs on the server only, and its license is All rights reserved. World of Chaotic Blocks is also a Forge 1.20.1 mod, but it is server-side only under the MIT License. Random World Blocks targets 1.20.1 on Forge and runs on client and server under the MIT License, so it touches both sides like Complete Chaos does.
