But to be fair, Sony copied Nintendo and then MS copied Sony, so if Nintendo copied MS, they are well within their rights
Pretty much this, but even still it's Nintendo's layout to begin with and it's really hard to copy your own controller when it was yours originally. The only thing that anyone can say Nintendo copied was adding a second stick, and even that's debatable since the C buttons on the N64 controller pretty much did the same thing as another analog stick, as Nintendo intended them to.
I remember I was in a car with my nephews and nieces once and I heard a Michael Jackson cover come on the radio. I remarked on it and they jumped down my throat saying that I had to have been wrong, that Michael Jackson must have copied it from them.
It was hilarious but also sad and depressing at the same time. There really doesn't seem to be any kind of history anymore. Things happen, they pass, and they're forgotten. Just like how without Nintendo Sony and MS wouldn't even be in this industry and consoles, if anyone would even still be making them, would probably still be using some sort of uncomfortable joystick.
