I only have played nintendoland but I also have Zombi U so I cant say yet

funky barn

NSMBU without a doubt :D.

I have Nintendoland, Monster Hunter and Need for Speed, but I'm not enjoying any one of them.

Probably Lego City Undercover, surprised how fun it is

A little off topic, but I've seen Lego City for the first time at a store, and I noticed massive jaggies.

Was it a poor set up, or the game completely lacks any sort of aliasing ?

after finishing it ofr a second time I must say that NSMBU is a great game - the challenges are very challenging an dit looks great -

both latest "NSMB" entries are the best so far.

I know many people will not agree with me, but I do believe that Lego City is the best WiiU game so far.
Many people ignore this game due to its "kiddie" appearance, but the game has a lot of surprises, has great voice acting, great graphics. Very, very few glitches. It´s the kind of game that we see the effort of the development team in every detail.
Need For Speed Most Wanted, AC3, NSMBU and JD4 all come close.

Why isn't Nintendo Land on the poll?!?! noob

I really like LEGO City...but I also enjoy NintendoLand, ZombiU and Runner 2. Hmm...
