BuildCraft

BuildCraft is a mod that uses machines to harvest, manipulate, and automatically craft items. It also has machines that can automatically build structures based on blueprints. BuildCraft uses engines to power these machines. It also introduces two new liquids, oil and fuel, to power combustion engines, in addition to traditional fuel sources of coal.
