Don't worry bud, I'm with you.
To the guy saying it's been like that for virtually all games, well, you're wrong..
the SNES Mario Kart. The original game. It uses the easiest button to attend to w/ a human thumb. The one right in the center.
The B button.
Look at that.
WiiU Gamepad has the same layout!
Mario Kart 64 also uses the button directly in the center.. the A button. The B button in this case is comparable to the SNES's Y button.
Mario Kart Double Dash uses the A button, but it's also the single most center button on the entire controller, and it's enormous. The button to it's direct left is the brake button.
I don't know about the Wii game. It sucked... However, I actually ran it in dolphin later, with custom controls (seriously... by default, they want the trick buttons mapped to the dpad? What on earth?) and I had a lot more fun with it.
Back to Mario Kart 8, it's also unnerving that there's no accessible brake button while using the nunchuk wiimote combo. What the heck? I like to tap the brake while drifting around tight corners, if I find I'm not making the turn all that well. It works great.. But I've had defense hordes tell me you don't need to ever use the brake button, and I guess that's a good enough reason why I shouldn't be complaining? How about you let me customize the god damn controls, or, at least give all functions to all controllers you support. Geez.
Anyway, the button thing w/ Nintendo is a huge pet peeve of mine...
Kirby Super Star on the SNES uses Y + B for attack/jump.
So does Mario in Mario World... so does Yoshi's Island....
So it baffles me to no end why the new games in these series do NOT use this method for controls! . Instead, the Y+B functions are now mapped to B+A..
My girlfriend recently got Yoshi's New Island and complained about the controls. I agreed with the problem, found a change of controls option in the game controls menu, and fixed that shit right up..
I popped my game in... Kirby's Triple Deluxe.. I thought, well, it's this shit again.. I'll just go into the controls and set it right. But no... You CAN'T. It's maddening.
I also got Donkey Kong Returns on 3DS as a platinum Club Nintendo member.. Mind blowingly, when you change the buttons how they'd be mapped in any other Donkey Kong Country game (SNES), it also forces you to use the circle slider.. Which is awful. I said it. Why can't I just change the buttons? Why are you forcing circle slider on me because I prefer Y+B, as Nintendo standardized w/ the SNES??
