I’m pretty sure that by this point Nintendo is used to being one of the giants on whose shoulders many other video game developers stand. After all, just about every platformer or action RPG owes a debt to the company’s Mario and Zelda franchises, and its Metroid series was so influential in the design of similar exploration-heavy titles that gamers just threw their hands up and decided to call the genre “Metroidvania” (somewhat unfairly giving half the credit to Konami’s Castlevania, which wasn’t nearly as groundbreaking in establishing the category).
Still, it’s one thing when some third-tier software publisher or homebrew video game outfit toes the line between being inspired by your creation and outright copying it, and another when it’s world-famous Disney.
