Conclusion:
Super Smash Bro. Wii U plays terrific. If you descend in it and get used to his favored method of control, they say: practice! Practice! Practice! It's like the predecessor designed for Nintendo characters but also send other companies some fighters going. Capcom with MegaMan or Namco Pac-Man to name just two of them.
In previous Smash Bros. titles the GameCube controller was current. Nintendo has considered this and has an adapter for this to.
For my part I had accustomed myself to this controller, but wanted to give the newly acquired Wii U Pro Controller a chance and can say from my own experience: You get used to it. The advantage is that you can customize the control keys. The online experience is different. Sometimes lagt / jerky / not delayed it while fighting, sometimes.
Nintendo is trying to keep this item as Mario Kart 8 fresh and offers downloadable additional contents (costumes for Mii fighter, characters, etc.) that are not mandatory.
