This was posted a couple days ago but I haven't seen it on this forum.
So it looks like playing with two game pads at once will affect the performance.
I am disappointed. If someone else wants to play New Super Mario Bros. U with me, they are going to want to play with a game pad. But doing this will affect the performace.
Hopefully the effects won't be easily noticable.
