New news/rumor about Nintendo Land in Japan: Guests will wear magnetic electronic bracelets that interact with setpieces and characters all over the land, as well as the Mariokart and Yoshi rides. You get points for every interaction, and then you can transfer those points to games you're playing at home on the Switch (and/or the next Nintendo console) for bonus items (or something).
Yeah, it's gimmicky, but I think it's also a clever optional way to make the land feel like a living game. I wonder if we'll get any kind of scaled down version of this for Hollywood (Epic Universe will get it all and more, I'm sure).
