Cadence of Hyrule is a mash-up that no one saw coming. It was a complete surprise in so many ways, most of which was the game being a collab between Nintendo and an indie studio. It's uncharted territory for the Big N, but definitely shows that the company is embracing some new ideas as far as IP utilization.
One big-name dev who was just as surprised to see this game announced was none other than Yuji Naka. Mr. Naka said that some time ago, he proposed an idea to Nintendo that would have him working with Mario in some way. Nintendo was quick to shoot down the proposal, and that was that. Seeing as how Nintendo is allowing an indie dev to work with the Zelda license goes to prove that the Nintendo of old, at least in some ways, is no longer a thing.
