If you already own it, I wouldn't recommend picking this up even if you are fancying a second playthrough and own it elsewhere (why waste the money on a game you already have?) but for first timers, go for it. It's fun, well made, and hopefully if it does well, we'll see some sequels set in their weird post-human no-electricity world.
Super Mario 3D World
Super Mario 3D World is both gorgeous and about as enjoyable as a video game can be. There is an immense amount of depth that kept me coming back for more, time and time again. This is the rare type of game that I believe ten years down the road we will be coming back and playing again and again. It’s that good. For all those worried that the Wii U was going to fall into some dark oblivion, fret not, your savior is here and its Super Mario 3D World one of the best platformers ever made.
New Super Luigi U
For a third of the price of the main game, you essentially double the length. You get a whole new slew of 80 levels that takes about as long as the main game to get through, and has even more to do because it's just so amazingly difficult. While some of the visual elements feel a little pasted-in, New Super Luigi U adds enough fresh things to an already excellent base game to be more than worth your time.
Epic Mickey 2: The Power of Two
Time is valuable and is often constrained by a number of reasons, whether they be personal/social concerns or even a busy release schedule. I want to be as explicit as possible and say that Epic Mickey 2 is not worth your time. A bad camera system, a poor help system, bad AI and the lack of substantial Wii U features make this game dull, uninteresting and frustrating.
