Immersive Engineering is a tech mod with a certain charm, based on the ideas and concepts, and with most assets created by Damien Hazard.
Overall, it's about realism-inspired technology: Instead of glowing red tubes, it offers actual, hanging powerlines. Instead of one block that magically spits out dusts when ore is put in, it offers a crusher, a big multiblock (5x3x3) that features rotating wheels and spits out particles as it breaks the ore. Instead of a Laser that turns power into magical light and ores, it offers an Excavator, another massive, resource intensive, multiblock (3x7x8) which digs ores out of the ground with a big rotating bucketwheel.
IE is about making tech mods more balanced and more pretty, and adding its own twist by going for retro-futurism (think BioShock, Order 1886, SkyCaptain and the World of Tomorrow) rather than clinical white+grey future cubes. The mod features Power Generation in forms of waterwheels, windmills, biodiesel and more and many of its machines are multiblocks!
