The industry part of Advanced Autonomous Industries. Adds motors, powered offshore pumps, burner labs, and more. Alters tech and recipes. Additional features will be added gradually. Other AAI mods are not required.
Also be wary, ie in minecraft, that road leads down the path of microcrafting hell. I feel like the amount of complexity added with the current version of motors and electrical motors is a nice amount, but more on top could become particularly nasty (Esp early-game assembling machines) and ie marathon types of world.
