It isn't, because... You're already too busy with AAA releases
Even if you get the Wii U, and buy all the best launch games, you likely won't have time to play them all. This holiday season is bananas (B-A-N-A-N-A-S), with over a dozen high-profile games releasing over the course of the next few months. If you're into military shooters you have Call of Duty: Black Ops 2, Medal of Honor: Warfighter, and a little game called Halo 4 staring at you, and if you're more of a fan of adventure games then you've got Assassin's Creed III and Hitman: Absolution right there, waiting to be played. Begging to be played.
Oh, and XCOM, and Dishonored, and Resident Evil, and... well, lots of games. And then it's 2013, and you're playing Tomb Raider, Dead Space 3, and another ten AAA titles in the first few months. You just might not have the time for ZombiU.
