That's because this launch-window release for Nintendo's next console will feature a Balloon Fight-based mini-game that uses an art style similar to that of Kirby's Epic Yarn and that can be played solo (as opposed to pretty much every other Nintendo Land mini-game unveiled so far, save "Donkey Kong's Crash Course").
To see it in action, head on over to gameinformer.com and watch the trailer that was uploaded yesterday afternoon.
Will this mini-game, called "Balloon Trip Breeze," also contain a multi-player mode? The folks at Game Informer don't seem to know, unfortunately. Personally, I hope it does--despite the fact that it's likely I'll be playing Nintendo Land (and practically every other Wii U game I purchase) all by myself.
