Define...success.
I would say so. It grabbed the motion controller gig and ran with it and capitalized on the huge market of the casual gamers, who we can assume that most of the younger casual gamers will grow to become core gamers. Wii U is suppose to be a more mature gaming console than the Wii so as their fanbase grows (in age), so will their games.
To stay on topic and keep it simple, it was a big success, no denying.
