While this is absolutely awesome and a welcome addition, as is the new playable character Nabbit, it is somewhat disappointing that they didn’t come up with a new story or at least a cool twist on the story.
Now that you are controlling Luigi, they could’ve made Waluigi star in a core Mario game for the first time, and finally developed Daisy into her own character. Sadly that isn’t the case. Maybe in a second piece of Downloadable Content?
Doubtful but I hope that Nintendo listens to the guy who suggested this idea in the youtube comments, as it’s a great idea and something Nintendo should explore in the future!
