Not taking a shot against the game, but I seem to be playing games specifically on the game pad vs the traditional way of controller + TV, and ZombiU needs both the TV and the game pad. I just got Batman on Monday, and I've put more hours into that than ZombiU which I've had since launch.
The only downside to Batman is that you have to enter Game Pad mode every single time the game is booted up; where as, games like AC3, NSMBU, Darksiders 2, etc. either a.) recognize that the TV is not on/not on the right INPUT mode, or b.) save the preferences with the save game and load the game specifically on the Game Pad when starting up.
