This mod adds way too many ways to get dirt, and some of the stuff in here would probably take years to actually get. There are also a crazy amount of different dirt blocks to discover and experiment with.
There is also a goal to this mod. The goal is to build a house out of the block named "Powerful".

what this mod adds:

This mod adds a bunch of dirt-based crafting and progression, letting you slowly turn dirt into more useful stuff.
Some examples of things you can make:

• Dirt wood
• Grass ore
• Cobblestone recipes
• Sand recipes
• Sapling recipes
• etc.

Basically: a ton of possibilities using only dirt.

recommended mods

I reccomend using Just Enough Items (JEI) and Chipped while playing this.
Otherwise trying to figure out the recipes will probably make you never want to download a mod again.

how to play:

Make a completely void world.
Turn structures off.
Give yourself a 5 block tall pillar of dirt.

From there you have to figure out how to progress using all the weird dirt stuff this mod adds.

warning:

this mod is really hard. Some things might take an absurd amount of time to get. Only play it if you’re actually up for a challenge.
