LEGO has produced various seasonal and holiday-themed sets over the years. These sets often coincide with holidays like Christmas, Easter, Halloween, and Valentine's Day, among others. The LEGO Basic theme, which began in the 1970s, was designed to be a more general, non-thematic series of sets. Unlike the themed sets that revolve around concepts, the Basic theme provided a collection of standard LEGO bricks and pieces.
1997 LEGO Sets
1997 saw LEGO’s first major sales decline, prompting experimentation and digital expansion. LEGO Island introduced the brand’s first open-world video game, setting the stage for future digital storytelling. New subthemes included Divers for underwater exploration, Fright Knights for gothic medieval fantasy, and Time Twisters as a sequel to Time Cruisers. LEGO Space added Roboforce and UFO, shifting toward alien-focused designs, while Aquazone expanded with Aquaraiders. Despite challenges, LEGO’s creativity remained strong across both physical and emerging digital platforms.
