Donkey Kong Bananza, probably my favorite game of the year, is getting a paid expansion today called DK Island & Emerald Rush. As the title implies, you'll get to explore the island where Donkey Kong hails from and visit a whole host of his friends while you're at it. Naturally, there is more to explore and find there, but there's also a whole new set of challenges once you've finished the main game story. That's the titular Emerald Rush.
Loosely characterizing Donkey Kong Bananza in this manner misses the point of what makes the game so enjoyable to play. Bananza is a breeze for players because it's built on a framework that is versatile and complex yet accessible and intuitive. By giving you all the tools you need to succeed in Bananza's vast sandbox, Nintendo made a game that feels effortless to punch your way through. If you think the game is easy, then it's doing its job correctly--Nintendo wants it to feel easy.
