I've been thinking about it since it's the first Nintendo cross-platform title. If you buy it for 3DS, you can also play it on your Wii U. And vice versa. It's really gonna depend on the price. Above $20 I'm gonna pass it up, at least for a while. The Miiverse "tipping" system seems great though, kinda how Mario Maker is going to be with sharing your creations and receiving feedback. We'll see!
