I frankly don't know what to think of this. The game in and of itself does look fun, but not $250/$60 fun, as this is the kind of thing that would go for like ~$1 or be free for iOS/Android. I'm also not sure about having to switch from looking at the pad to looking at the TV screen, as it would probably just end up confusing me. And mind blown at using a stylus on the pad. Wasn't aware of that until now, heh.
It's no wonder people thought WiiU was just a controller; apparently nobody watched the conference/announcement trailer
