In addition to the Gummi Ship minigame, minigames feature prominently in certain worlds. While Atlantica is a normal world in "Kingdom Hearts", albeit with a special "underwater" control scheme, it becomes an interactive rhythm game in "Kingdom Hearts II" which is completely unrelated to the overall story and serves as mere filler. Finally, Space Paranoids features a Light Cycle mini-game that strongly deviates from the original film. Nomura included this minigame because he knew people associated the Light Cycles with "Tron".
