The Ultimate Collector's Series, or UCS, is a LEGO subtheme of Star Wars introduced in 2000 and was meant to be more detailed and aimed at older builders. These Ultimate Collector's Series sets tend to be larger, and more expensive than typical sets.
2021 LEGO Sets
In 2021, LEGO continued its trajectory of product expansion and innovation. One notable addition was the "LEGO VIDIYO" theme, introduced in partnership with Universal Music Group, which combined physical sets with a digital music video making experience. The company also expanded the "LEGO Art" series, allowing adults and older fans to create wall art based on various franchises. Existing themes like "Star Wars," "City," "Technic," and others received new set additions. Sustainability efforts were underscored with the announcement of prototype bricks made from recycled plastic.
