For good creative play, they have to limit the diversity of pieces and colours within a single theme. Different sets from the same theme need to have similar pieces in the same colour scheme so they can co-exist nicely. Take these 3 sets from the classic 1990s Pirates, for example: 6259 "Broadside's Brig" https://brickset.com/sets/6259-1/Broadside-s-Brig https://brickset.com/sets/6259-1/Broadside-s-Brig 6267 "Lagoon Lock-up" https://brickset.com/sets/6267-1/Lagoon-Lock-Up https://brickset.com/sets/6267-1/Lagoon-Lock-Up 6265 "Sabre Island" https://brickset.com/sets/6265-1/Sabre-Island https://brickset.com/sets/6265-1/Sabre-Island Combining these 3 on a big baseplate can give you something completely new and interesting that still belongs to the Pirate theme. The bulk of the parts are white and yellow-coloured bricks for walls and architectural elements.
