The LEGO Creator theme consists of a variety of subthemes that revolve around sets that focus on buildings, creatures, vehicles, robots and recently more specialized sets such as botanical and even the Chinese New Year. Many of these sets have fallen under the 3-in-1 label which include instructions in a single set to provide multiple alternative models. Originally created in 2001 with a focus on larger bucket sets, the LEGO Creator theme has expanded outside just bricks to later include minifigures.
2019 LEGO Sets
There were a number of events in 2019 that helped shaped the investment market for LEGO. Probably the most important event is that LEGO Star Wars celebrated its 20th anniversary. In addition, LEGO released new themes such as Hidden Side, Overwatch and a set based on the Netflix series Stranger Things. Sadly the Nexo Knights and Elves themes were discontinued in 2019.
