Differences
Notice: this is a port of Earthworks to 1.16+. Backports and support for older versions are not planned at this time.
Some features may have been changed to adapt to modern versions, but all blocks and items have been ported to the best of my knowledge.
In addition, items/blocks no longer disable themselves in the presence of extra mods, neither are extra recipes for other mods added. This is because datapacks can handle these without any other mods required.
Overview
Earthworks aims to add earthen and ancient and prehistoric inspired building materials to Minecraft.
Taking cues from the Stone Age, Bronze Age, and Iron Age, Earthworks adds some of the first materials mankind used to craft. Materials like wattle and daub, wicker, rammed earth, and adobe bricks. These are crude materials, fashioned out of what was at hand, and easily accessible, but prove to be as strong as stone when fashioned properly. Utilizing these in an early build will provide some excellent shelters.
Some materials you will have to work harder for, such as concrete, cinder blocks, or cordwood, but these materials will prove expansive, and help you to forge a great empire like our Roman ancestors. These materials will yield more when crafted, pushing your roads and aqueducts further and further.
