My opinion has changed. Before, we had little info on NSMB2. I was thinking U would be much better because of it's cool features with the Gamepad. You could just turn off the TV and continue playing, which I thought was really cool. I also like being able to have those platforms that the other player creates. But now we have a lot more information on NSMB2, and it has things much better than U. It has DLC, which I find awesome. It has the Coin Rush mode, which will help make the game last really long. Anyway, it has lots of features that are better than U, so, I'm gonna go with New Super Mario Bros. 2.
