Tying a lot of these disparate elements - from the Freegan trait, new Civil Design and Freelance Crafting careers and a secondary currency called Bits & Pieces - together is the new Fabrication skill. With a lot of new features and no previous-gen version of the expansion to act as a touchstone, it's easy for even experienced Sims players to feel like they're starting from scratch learning completely new mechanics. It's also one of the biggest departures from tried-and-tested expansion formulas for The Sims 4 in recent years. The expansion builds on the eco-friendly themes already present in Island Living, Tiny Living, and Laundry Day and places them front-and-centre. The Sims 4 fabricator and fabrication skill is part of The Sims 4: Eco Lifestyle expansion pack, which released in June 2020.
