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.
2004 LEGO Sets
2004 was a pivotal recovery year following financial losses in 2003. LEGO updated its color palette, introducing light nougat for licensed minifigures and brighter grays and browns. The company partnered with Ferrari under LEGO Racers and launched Knights’ Kingdom II, a story-driven reimagining of Castle. QUATRO expanded the preschool range, while World City, Orient Expedition, Spider-Man, and Gravity Games concluded. These shifts, along with strategic licensing, began LEGO’s long-term turnaround.
