Welcome to Create, a mod offering a variety of tools and blocks for Building, Decoration, and Aesthetic Automation.
The added elements of tech are designed to leave as many design choices to the player as possible. With Create, the game isn't played inside a bunch of UIs, it challenges you to set up contraptions of animated components working together in many possible arrangements.
Create's visual in-game documentation called 'Ponder' will guide you through all added mechanics and gadgets.
