1998 LEGO Sets
1998 marked LEGO’s leap into programmable play with the launch of LEGO Mindstorms, combining motors, sensors, and code for user-built robots. LEGO also entered digital entertainment with games like LEGO Creator, LEGO Loco, and LEGO Chess. New themes included Adventurers, following Johnny Thunder’s global expeditions, and Insectoids, a sci-fi successor to Exploriens. LEGO Castle revisited classic factions such as Crusaders and Dragon Masters, reconnecting with its medieval roots while bridging into modern set design.
