You've got to be kidding me, right? This isn't Universal becoming a gaming studio, or even the park becoming game-centric, it's about bringing amazingly iconic characters into the parks that reach as broad a demographic as Mickey and friends, and creating amazing experiences on the level of Diagon and Hogsmeade based around them. Why don't Mario, Pikachu, Zelda, and company "deserve" the "Universal treatment?" Give me one, solid, reasonable answer that isn't just "I don't like the IP" or "it isn't a movie."
This makes absolutely zero sense, at all. I don't really like Frozen that much, but I'm definitely excited about the additions for it over in Tokyo, because it will be done right and be amazing. The same will go for Nintendo at Universal.
