Track your addiction
Not that we're addicted to games, but we'd probably go insane if we couldn't play them anymore. That's not bad, is it? Luckily, if we ever start to get worried, we can keep track of our habits directly using the Wii U's new statistics application.
It'll tell you if you spent two hours watching Netflix yesterday, or played 200 hours of Black Ops 2 last month. Whether you should be worried about that is a personal choice.
