I just watched Bayonetta 2 trailer and first came image of playing the game on Wii motion controls.Then I was like, what controller does Wii U actually have?Oh yea, gamepad is the controller..I don't really know that much about the console..

It looks pretty much same as Bayonetta, even same controls and he is playing ok.

So how good is Wii U gamepad as a controller, compared to current ones?Now that we have new controls for Ps4/One.

I played Bayonetta on hard few months ago again (epic stuff) on my Dualshock 3.I don't know better controller for that, tho almost threw one from a window in first few levels..

I haven't tried one yet, to me it just looks too dayyym big and hard to use in games like Bayonetta, where everything must be timed in microseconds.
