WhenKingdom Heartsfirst debuted in 2002, the idea of a crossover between Disney’s whimsical worlds and Square Enix’s brooding, JRPG aesthetics seemed almost absurd. Yet over 20 years later, Kingdom Hearts has become a beloved and iconic franchise, spawning thirteen games, multiple manga adaptations, a trove of collectibles, and a deeply loyal fanbase.
As its influence grew, other game developers (many fans of the series themselves) began to take notice. Over time, they started slipping Kingdom Hearts Easter eggs and subtle references into their own titles, a quiet homage to a series that defied expectations and redefined crossover storytelling in gaming.
