Just for those who still think that there are'nt enough buttons for the video games to be in-depth enough to be played. Here's a bit of information for you:
Nintendo Gameube Nintendo Revolution
A Button A Button
B Button B Trigger
X Button X (a) Button
Y Button Y (b) Button
L Button Z1 Trigger
R Button Z2 Trigger
Z Button Select Button
Start / Pause Button Start Button
Also the number of analog sticks and directional pads is'nt different either:
Analog Stick Analog Stick
C Stick Pointer
Directional Pad Directional Pad
Anything else? Lol!
And I know that the X (a) and Y (b) buttons may be too far to be pushed often. But remember the controller is still in development and they could also be used for unimportant uses likes maps or whatnot. So no need to worry. As you can see there are MORE buttons than the Gamecube so it won't be a problem for SSBR!
